FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –



Part 26: Sectional specification – Fixed aluminium electrolytic

capacitors with conductive polymer 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 60384-26 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
The text of this standard is based on the following documents:
FDIS Report on voting
40/2052/FDIS 40/2062/RVD

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

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 drawings 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.
Normally the numerical values shall be given for cylindrical types, the body diameter, and the
length and diameter, and the spacing 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 Rating 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 Nominal capacitance range
See 2.2.1.
NOTE When products approved to the detail specification have different ranges, the following statement should
be added:
"The range of values available in each voltage range is given in QPL (qualified products list)."
1.4.3.2 Particular characteristics
Additional characteristics may be listed, when they are considered necessary to specify
adequately the component for design and application purposes.
