Fixed capacitors for use in electronic equipment - Part 11: Sectional specification - Fixed polyethylene-terephthalate film dielectric metal foil DC capacitors

IEC 60384-11:2019 is applicable to fixed direct current capacitors, for rated voltages not exceeding 6 300 V, using as dielectric a polyethylene-terephthalate film and electrodes of thin metal foils. For capacitors with rated voltages exceeding 1 000 V, additional tests and requirements may be specified in the detail specification. 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. The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1:2016 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification are of an equal or higher performance level. Lower performance levels are not permitted. 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.

Standard EN-IEC 60384-11 se uporablja za fiksne kondenzatorje za enosmerni tok z nazivnimi napetostmi, ki ne presegajo 6300 V, ki kot dielektrik uporabljajo polietilenski tereftalatni film in elektrode iz tankih kovinskih folij. Za kondenzatorje z nazivno napetostjo, višjo od 1000 V, so lahko v podrobni specifikaciji določeni dodatni preskusi in zahteve. Kondenzatorji, zajeti v tem dokumentu, so namenjeni uporabi v elektronski opremi. Kondenzatorji za preprečevanje elektromagnetnih motenj niso vključeni, vendar so zajeti v standardu IEC 60384-14. Cilj tega dokumenta je predpisati prednostne vrednosti in lastnosti, izbrati primerne postopke za ovrednotenje kakovosti, preskuse in merilne metode iz standarda IEC 60384-1:2016 ter podati splošne zahteve glede zmogljivosti za ta tip kondenzatorja. Preskusne stopnje in zahteve, predpisane v podrobnih specifikacijah, ki se navezujejo na to področno specifikacijo, so na enaki ali višji ravni učinkovitosti. Nižje ravni učinkovitosti niso dovoljene.

FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –

Part 11: Sectional specification – Fixed polyethylene-terephthalate
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 60384-11 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This fourth edition cancels and replaces the third edition published in 2008. 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.

Capacitors for electromagnetic interference suppression are not included, but are covered
by IEC 60384-14.
The object of this document is to prescribe preferred ratings and characteristics and to select
from IEC 60384-1:2016 the appropriate quality assessment procedures, tests and measuring
methods and to give general performance requirements for this type of capacitor. Test
severities and requirements prescribed in detail specifications referring to this sectional
specification are of an equal or higher performance level. Lower performance levels are not
permitted.
