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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 60384-22 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This third edition cancels and replaces the second edition published in 2011. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous

4 Information to be given in a detail specification
4.1 General
The detail specifications shall be derived from the relevant blank detail specification.

– 10 – IEC 60384-22:2019 © IEC 2019
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.
The information given in 4.2 may be presented in tabular form if more convenient.
The information in 4.2 to 4.5 shall be given in each detail specification and the values quoted
should be selected from those given in the appropriate clause of this sectional specification.
4.2 Outline drawing and dimensions
There shall be an illustration of the capacitors as an aid to easy recognition and for
comparison of the capacitors with others.
Dimensions and their associated tolerances, which affect interchangeability and mounting,
shall be given in the detail specification. All dimensions shall be stated in millimetres,
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, width and height of the body.
When necessary, for example when a number of items (sizes and capacitance/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 capacitors.
4.3 Mounting
The detail specification shall give guidance on methods of mounting for normal use. Mounting
for test and measurement purposes (when required) shall be in accordance with 8.4 of this
sectional specification.
4.4 Rating and characteristics
4.4.1 General
The ratings and characteristics shall be in accordance with the relevant clauses of this

sectional specification, together with 4.4.2, 4.4.3 and 4.4.4.
4.4.2 Nominal capacitance range
See 6.2.4.1.
When products approved to the detail specification have different ranges, the following
statement should be added: "The range of capacitance values available in each voltage range
is given in the register of approvals, available for example on the IECQ on-line certificate
system website www.iecq.org".
4.4.3 Particular characteristics
Additional characteristics may be listed, when they are considered necessary to specify
adequately the component for design and application purposes.
4.4.4 Soldering
The detail specification shall prescribe the test methods, severities and requirements
applicable for the solderability and the resistance to soldering heat tests.

4.5 Marking
The detail specification shall specify the content of the marking on the capacitor and on the
packaging. Deviations from Clause 5 of this sectional specification shall be specifically stated.
5 Marking
5.1 General
See IEC 60384-1:2016, 2.4, with the details of 5.2 to 5.6.
5.2 Information for marking
The information given in the marking is normally selected from the following list; the relative
importance of each item is indicated by its position in the list:
– nominal capacitance;
– rated voltage (DC voltage may be indicated by the symbol:   [IEC 60417-5031(2002-10)]
or    );
– tolerance on nominal capacitance;
– dielectric subclass as applicable (in accordance with 6.2.5);
– year and month (or week) of manufacture;
– manufacturer's name or trade mark;
– climatic category;
– manufacturer's type designation;
– reference to the detail specification.
5.3 Marking on the body
These capacitors are generally not marked on the body. If some marking can be applied, they
shall be clearly marked with as many as possible of the items stated in 5.2 as is considered
useful. Any duplication of information in the marking on the capacitor should be avoided.
5.4 Requirements for marking
Any marking shall be legible and not easily smeared or removed by rubbing with fingers.
5.5 Marking of the packaging
The packaging containing the capacitor(s) shall be clearly marked with all the information
listed in 5.2.
5.6 Additional marking
Any additional marking shall be so applied that no confusion can arise.
6 Preferred ratings and characteristics
6.1 Preferred characteristics
Preferred climatic categories only shall be given in the preferred characteristics.
The capacitors covered by this document are classified into climatic categories in accordance
with the general rules given in IEC 60068-1:2013, Annex A.

– 12 – IEC 60384-22:2019 © IEC 2019
The lower and upper category temperatures and the duration of the damp heat, steady state
test shall be chosen from the following:
– lower category temperature: −55 °C, −40 °C, −25 °C, −10 °C and +10 °C;
– upper category temperature: +70 °C, +85 °C, +100 °C, +125 °C and +150 °C;
– duration of the damp heat,
steady state test (40 °C, 93 % RH): 4, 10, 21 and 56 days.
The severities of the cold and dry heat tests are the lower and upper category temperatures
respectively.
NOTE The resistance to humidity resulting from the above climatic category is for the capacitors in their
unmounted state. The climatic performance of the capacitors after mounting is greatly influenced by the mounting
substrate, the mounting method (see 8.4) and the final coating.
6.2 Preferred values of ratings
6.2.1 Rated temperature (T )
R
The rated temperature is equal to the upper category temperature for capacitors with the
upper category temperature not exceeding 125 °C, unless otherwise stated in the detail
specification.
6.2.2 Rated voltage (U )
R
The preferred values of the rated voltage are the values of the R5 series of ISO 3. If other
values are needed they shall be chosen from the R10 series.
The sum of the DC voltage and the peak AC voltage or the peak to peak AC voltage,
whichever is the greater, applied to the capacitor shall not exceed the rated voltage.
