FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –

Part 15: Sectional specification:
Fixed tantalum capacitors with non-solid or solid electrolyte

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 60384-15 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This second edition cancels and replaces the first edition published in 1982,
Amendment 1:1987 and Amendment 2:1992, and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Revision of the structure in accordance with ISO/IEC Directives, Part 2:2016 (seventh
edition) to the extent practicable, and harmonization between other similar kinds of
documents.
b) In addition, Clause 4 and all the tables have been reviewed in order to prevent duplications
and contradictions.

2.2.8 Rated temperature
The standard value of the rated temperature is +85 °C unless otherwise specified in the detail
specification.
3 Quality assessment procedures
3.1 Primary stage of manufacture
For capacitors with solid electrolyte, the primary stage of manufacturing is the formation of the
oxide layer.
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 test records of released lots
The information required in IEC 60384-1:2016, Q.1.5, shall be made available when
prescribed in the detail specification and when requested by a purchaser. After the endurance
test, the required parameters are the capacitance change, tangent of loss angle and leakage
current.
3.4 Qualification approval procedures
3.4.1 General
The procedures for qualification approval testing are given in IEC 60384-1:2016, Q.2
The schedule to be used for qualification approval testing on the basis of lot-by-lot and
periodic tests is given in 3.5. The procedure using a fixed sample size schedule is given in
3.4.2 and 3.4.3.
3.4.2 Qualification approval on the basis of the fixed sample size procedure
The fixed sample size procedure is described in IEC 60384-1:2016, Q.2.4. The sample shall
be representative of the range of capacitors for which approval is sought. The samples may
be the whole or part of the range given in the detail specification.
The sample shall consist of four specimens having the maximum and minimum voltages and
for these voltages the maximum and minimum case size. When there are more than four case
sizes, an intermediate case size shall also be tested. In each of these case size/voltage
combinations (values), the maximum 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 fewer than
four values, the number of specimens to be tested shall be that required for four values.
Spare specimens are permitted as follows:
Two (for 6 values) or three (for 4 values) per value may be used as replacements for
specimens, which are non-conforming 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.

IEC 60384-15:2017 © IEC 2017 – 13 –
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.
Table 2 gives the number of samples to be tested in each group or subgroup together with the
permissible number of non-conforming items for qualification approval tests.
3.4.3 Tests
The complete series of tests specified in Table 2 and Table 3 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 non-conforming in the tests of Group 0 shall not be used for the other
groups.
Approval is granted when the number of non-conforming items is zero.
Table 2 and Table 3 together form the fixed sample size test schedule for the qualification
approval on the basis of the fixed sample size procedure.
Table 2 gives the number of samples and permissible non-conforming items for each tests or
test groups.
Table 3 gives a summary of the test conditions and performance requirements, and choices of
the test conditions and performance requirements in the detail specification.
The test conditions and performance requirements for the qualification approval on the basis
of the fixed sample size procedure should be identical to those for quality conformance
inspection given in the detail specification.
