IEC 60384-13:2020 specifies preferred ratings and characteristics, selects from IEC 60384-1:2016 the appropriate quality assessment procedures, tests and measuring methods, and gives general performance requirements for this type of capacitor. Test severities and requirements specified in detail specifications referring to this sectional specification are of an equal or higher performance level. Lower performance levels are not permitted. This part of IEC 60384 applies to fixed direct current capacitors, using as dielectric a polypropylene film with electrodes of thin metal foils. The capacitors covered by this document are intended for use in electronic equipment. Capacitors for electromagnetic interference suppression are not included, but are covered by IEC 60384-14. This edition includes the following significant technical changes with respect to the previous edition: a) revision of all parts of the document based on the ISO/IEC Directives, Part 2:2018, and harmonization with other similar kinds of documents; b) the document structure has been organized to follow new sectional specification structure decided in TC 40; c) revised tables and Clause 5 so as to prevent duplications and contradictions.

L’IEC 60384-13:2020 spécifie des valeurs assignées et des caractéristiques préférentielles, sélectionne, à partir de l’IEC 60384-1:2016, les procédures d’assurance de la qualité, les essais et les méthodes de mesure appropriées et spécifie les exigences de performances générales pour ce type de condensateur. Les sévérités d'essai et les exigences précisées dans les spécifications particulières sont d'un niveau supérieur ou égal à celui de la présente spécification intermédiaire. Des niveaux de performances inférieurs ne sont pas admis. La présente partie de l’IEC 60384 s’applique aux condensateurs fixes pour courant continu, utilisant comme diélectrique un film de polypropylène avec des électrodes de feuilles métalliques minces. Les condensateurs couverts par le présent document sont destinés à être utilisés dans des équipements électroniques. Les condensateurs d’antiparasitage ne sont pas inclus, mais sont couverts par l’IEC 60384-14. This edition includes the following significant technical changes with respect to the previous edition: a) revision of all parts of the document based on the ISO/IEC Directives, Part 2:2018, and harmonization with other similar kinds of documents; b) the document structure has been organized to follow new sectional specification structure decided in TC 40; c) revised tables and Clause 5 so as to prevent duplications and contradictions.

FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –

Part 13: Sectional specification – Fixed polypropylene
film dielectric metal foil DC capacitors

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 60384-13 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This fifth edition cancels and replaces the fourth edition published in 2011. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) revision of all parts of the document based on the ISO/IEC Directives, Part 2:2018, and
harmonization with other similar kinds of documents;
b) the document structure has been organized to follow new sectional specification structure
decided in TC 40;
c) revised tables and Clause 5 so as to prevent duplications and contradictions.

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
