FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

3 Quality assessment procedures
3.1 Primary stage of manufacture
For capacitors with solid electrolyte, the primary stage of manufacture is the etching or
formation of the anode body.
For capacitors with non-solid electrolyte, the primary stage of manufacture is the capacitor
manufacturer's evaluation of the formed anode foil.
3.2 Structurally similar components
Capacitors considered as being structurally similar are capacitors produced with similar
processes and materials, though they may be of different case sizes and values.
3.3 Certified records of released lots
The information required in 3.9 of IEC 60384-1 shall be made available when prescribed in
the detail specification and when requested by a purchaser. After the endurance test the
parameters for which variables information is required are the capacitance change, tan δ and
the leakage current.
3.4 Qualification approval procedures
The procedures for qualification approval testing are given in 3.5 of IEC 60384-1.
The schedule to be used for qualification approval testing on the basis of lot-by-lot and
periodic tests is given in 3.5 of this specification. The procedure using a fixed sample size
schedule is given in 3.4.1 and 3.4.2 below.
3.4.1 Qualification approval on the basis of the fixed sample size procedure
Sampling
The fixed sample size procedure is described in 3.5.3b) of IEC 60384-1. The sample shall be
representative of the range of capacitors for which approval is sought. This may or may not be
the complete range covered by the detail specification.
The sample shall consist of specimens having the lowest and highest voltages and, for these
voltages, the smallest and largest case size. When the range of rated voltages exceeds
200 V, an intermediate voltage shall also be tested. In each of these case size/voltage
combinations (values), the highest capacitance shall be chosen. Thus, for the approval of a
range, testing is required of either four or six values. When the range consists of less than
four values, the number of specimens to be tested shall be that required for four values.
Spare specimens are permitted as follows.
a) One per value which may be used to replace the permitted defective in Group 0.
b) One per value which may be used as replacements for specimens which are defective
because of incidents not attributable to the manufacturer.
The numbers given in Group 0 assume that all groups are applicable. If this is not so, the
numbers may be reduced accordingly.
When additional groups are introduced into the qualification approval test schedule, the
number of specimens required for Group 0 shall be increased by the same number as that
required for the additional groups.
– 12 – 60384-4 © IEC:2007(E)
Table 1 gives the number of samples to be tested in each group or subgroup together with the
permissible number of nonconforming items for qualification approval tests.
3.4.2 Tests
The complete series of tests specified in Tables 1 and 2 are required for the approval of
capacitors covered by one detail specification. The tests of each group shall be carried out in
the order given.
The whole sample shall be subjected to the tests of Group 0 and then divided for the other
groups.
Specimens found to be a nonconforming item during the tests of Group 0 shall not be used for
the other groups.
"One nonconforming item" is counted when a capacitor has not satisfied the whole or part of
the tests of a group.
Approval is granted when the number of nonconforming items does not exceed the specified
number of permissible nonconforming items for each group or subgroup and the total number
of permissible nonconforming items.
NOTE Tables 1 and 2 together form the fixed sample size test schedule, for which Table 1 includes the details for
the sampling and permissible nonconforming items for the different tests or groups of tests, whereas Table 2
together with the details of test contained in Clause 4, gives a complete summary of test conditions and
performance requirements and indicates where, for example, for the test method or conditions of test a choice
should be made in the detail specification.
The conditions of test and performance requirements for the fixed sample size test schedule should be identical to
those prescribed in the detail specification for quality conformance inspection.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60384-4 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This fourth edition cancels and replaces the third edition published in 1998 and its
amendment 1 (2000). This edition constitutes a minor revision related to tables, figures and
references.
This bilingual version, published in 2008, corresponds to the English version. It includes

FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 4: Sectional specification –
Aluminium electrolytic capacitors with solid (MnO )
and non-solid electrolyte
1 General
1.1 Scope
This part of IEC 60384 applies to aluminium electrolytic capacitors with solid (MnO ) and non-
solid electrolyte primarily intended for d.c. applications for use in electronic equipment. It
covers capacitors for long-life applications and capacitors for general-purpose applications.
Capacitors for special-purpose applications may need additional requirements.
Capacitors for fixed surface mount aluminium electrolytic capacitors are not included but they
are covered by IEC 60384-18.
1.2 Object
The principal object of this standard is to prescribe preferred ratings and characteristics and
to select from IEC 60384-1 the appropriate quality assessment procedures, tests and
measuring methods and to give general performance requirements for this type of capacitor.
Test severities and requirements prescribed in detail specifications referring to this sectional
specification shall be of equal or higher performance level, because lower performance levels
are not permitted.
1.3 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.

1.4 Information to be given in a detail specification
Detail specifications shall be derived from the relevant blank detail specification.
Detail specifications shall not specify requirements inferior to those of the generic, sectional
or blank detail specification. When more severe requirements are included, they shall be
listed in 1.9 of the detail specification and indicated in the test schedules, for example, by an
asterisk.
NOTE The information given in 1.4.1 may, for convenience, be presented in tabular form.
The following information shall be given in each detail specification and the values quoted
shall preferably be selected from those given in the appropriate clause of this sectional
specification.
1.4.1 Outline drawing and dimensions
There shall be an illustration of the capacitor as an aid to easy recognition and for comparison
of the capacitor with others.
Dimensions and their associated tolerances, which affect interchangeability and mounting,
shall be given in the detail specification. All dimensions shall preferably be stated in
millimeters; however, when the original dimensions are given in inches, the converted metric
dimensions in millimetres shall be added.
Normally, the numerical values shall be given for the length of the body, the width and height
of the body and the wire spacing, or for cylindrical types, the body diameter, and the length
and diameter of the terminations. When necessary, for example, when a number of items
(capacitance values/voltage ranges) are covered by a detail specification, the dimensions and
their associated tolerances shall be placed in a table below the drawing.
When the configuration is other than described above, the detail specification shall state such
dimensional information as will adequately describe the capacitor. When the capacitor is not
designed for use on printed boards, this shall be clearly stated in the detail specification.
1.4.2 Mounting
The detail specification shall specify the method of mounting to be applied for normal use and
for the application of the vibration and the bump or shock tests. The capacitors shall be
mounted by their normal means. The design of the capacitor may be such that special
mounting fixtures are required in its use. In this case, the detail specification shall describe
the mounting fixtures and they shall be used in the application of the vibration and bump or
shock tests.
1.4.3 Ratings and characteristics
The ratings and characteristics shall be in accordance with the relevant clauses of this
specification, together with the following.
1.4.3.1 Rated capacitance range

2.2.3 Rated voltage (U )
R
Preferred values of rated direct voltages taken from the R5 and R10 series of ISO 3 are:
For voltage values <250 V: 1 V, 1,6 V, 2,5 V, 4 V, 6,3 V and their decimal
multiples (R5 series), also 35 V, 50 V, 80 V and
200 V;
For voltage values ≥250 V: 250 V, 315 V, 350 V, 400 V, 450 V and 500 V
(250 V, 315 V, 400 V and 500 V are in accordance
with the R10 series; 350 V and 450 V are permitted
in addition).
2.2.4 Category voltage (U )
C
The category voltage is equal to the rated voltage, unless otherwise stated in the detail
specification.
2.2.5 Ripple voltage
An alternating voltage may be applied provided that the peak voltage resulting from the
alternating voltage superimposed on the direct voltage does not exceed the value of rated
direct voltage and that the rated ripple current (see 2.2.8) and the permissible reverse voltage
(see detail specification) are not exceeded.
2.2.6 Reverse voltage
The permissible reverse voltage shall be given in the detail specification.
2.2.7 Surge voltage ratio
The surge voltage shall be 1,15 times the rated or category voltage for rated voltages ≤315 V

3 Quality assessment procedures
3.1 Primary stage of manufacture
For capacitors with solid electrolyte, the primary stage of manufacture is the etching or
formation of the anode body.
For capacitors with non-solid electrolyte, the primary stage of manufacture is the capacitor
manufacturer's evaluation of the formed anode foil.
3.2 Structurally similar components
Capacitors considered as being structurally similar are capacitors produced with similar
processes and materials, though they may be of different case sizes and values.
3.3 Certified records of released lots
The information required in 3.9 of IEC 60384-1 shall be made available when prescribed in
the detail specification and when requested by a purchaser. After the endurance test the
parameters for which variables information is required are the capacitance change, tan δ and
the leakage current.
3.4 Qualification approval procedures
The procedures for qualification approval testing are given in 3.5 of IEC 60384-1.
The schedule to be used for qualification approval testing on the basis of lot-by-lot and
periodic tests is given in 3.5 of this specification. The procedure using a fixed sample size
schedule is given in 3.4.1 and 3.4.2 below.
3.4.1 Qualification approval on the basis of the fixed sample size procedure
Sampling
The fixed sample size procedure is described in 3.5.3b) of IEC 60384-1. The sample shall be
representative of the range of capacitors for which approval is sought. This may or may not be
the complete range covered by the detail specification.
The sample shall consist of specimens having the lowest and highest voltages and, for these
voltages, the smallest and largest case size. When the range of rated voltages exceeds
200 V, an intermediate voltage shall also be tested. In each of these case size/voltage
combinations (values), the highest capacitance shall be chosen. Thus, for the approval of a
range, testing is required of either four or six values. When the range consists of less than
four values, the number of specimens to be tested shall be that required for four values.
Spare specimens are permitted as follows.
a) One per value which may be used to replace the permitted defective in Group 0.
b) One per value which may be used as replacements for specimens which are defective
because of incidents not attributable to the manufacturer.
The numbers given in Group 0 assume that all groups are applicable. If this is not so, the
numbers may be reduced accordingly.
When additional groups are introduced into the qualification approval test schedule, the
number of specimens required for Group 0 shall be increased by the same number as that
required for the additional groups.
– 12 – 60384-4 © IEC:2007
Table 1 gives the number of samples to be tested in each group or subgroup together with the
permissible number of nonconforming items for qualification approval tests.
3.4.2 Tests
The complete series of tests specified in Tables 1 and 2 are required for the approval of
capacitors covered by one detail specification. The tests of each group shall be carried out in
the order given.
The whole sample shall be subjected to the tests of Group 0 and then divided for the other
groups.
Specimens found to be a nonconforming item during the tests of Group 0 shall not be used for
the other groups.
"One nonconforming item" is counted when a capacitor has not satisfied the whole or part of
the tests of a group.
Approval is granted when the number of nonconforming items does not exceed the specified
number of permissible nonconforming items for each group or subgroup and the total number
of permissible nonconforming items.
NOTE Tables 1 and 2 together form the fixed sample size test schedule, for which Table 1 includes the details for
the sampling and permissible nonconforming items for the different tests or groups of tests, whereas Table 2
together with the details of test contained in Clause 4, gives a complete summary of test conditions and
performance requirements and indicates where, for example, for the test method or conditions of test a choice
should be made in the detail specification.
The conditions of test and performance requirements for the fixed sample size test schedule should be identical to
those prescribed in the detail specification for quality conformance inspection.
