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 60384-21-1 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This standard and its related publications (CEI 60384-21, IEC 60384-22 and IEC 60384-22-1)
cancel and replace IEC 60384-10 (1989) and its Amendments 1 (1993) and 2 (2000) as well
as IEC 60384-10-1 (1989) and its Amendment 1 (1993).
The text of this standard is based on the following documents:
FDIS Report on voting
40/1421/FDIS 40/1452/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this standard may be issued at a later date.

The contents of the corrigendum of September 2004 have been included in this copy.

INTRODUCTION
Blank detail specification
A blank detail specification is a supplementary document to the sectional specification and
contains requirements for style, layout and minimum content of detail specifications. Detail
specifications not complying with these requirements may not be considered as being in
accordance with IEC specifications nor shall they so be described.
In the preparation of detail specifications the content of 1.4 of the sectional specification shall
be taken into account.
The numbers between square brackets on the first page of the detail specification correspond
to the following information, which shall be inserted in the position indicated.
Identification of the detail specification
(1) The “International Electrotechnical Commission” or the National Standards
Organization under whose authority the detail specification is drafted.
(2) The IEC or National Standards number of the detail specification, date of issue and
any further information required by the national system.
(3) The number and issue number of the IEC or national generic specification.
(4) The IEC number of the blank detail specification.
Identification of the capacitor
(5) A short description of the type of capacitor.
(6) Information on typical construction (when applicable).
(7) Outline drawing with main dimensions which are of importance for interchangeability
and/or reference to the national or international documents for outlines. Alternatively,
this drawing may be given in an annex to the detail specification.
(8) Application or group of applications covered and/or assessment level.
(9) Reference data on the most important properties, to allow comparison between the
various capacitor types.
