Fixed capacitors for use in electronic equipment - Part 14: Sectional specification - Fixed capacitors for electromagnetic interference suppression and connection to the supply mains

IEC 60384-14:2013 applies to capacitors and resistor-capacitor combinations which will be connected to an a.c. mains or other supply with nominal voltage not exceeding 1 000 V a.c. (r.m.s.) or 1 000 V d.c. and with a nominal frequency not exceeding 100 Hz. This fourth edition cancels and replaces the third edition published in 2005. It constitutes a technical revision. All changes that have been agreed upon can be categorized as minor revisions. The contents of the corrigendum of April 2016 have been included in this copy.

Condensateurs fixes utilisés dans les équipements électroniques - Partie 14: Spécification intermédiaire - Condensateurs fixes d'antiparasitage et raccordement à l'alimentation

La CEI 60384-14:2013 s'applique aux condensateurs et aux combinaisons condensateur/résistance qui sont connectés à un réseau d'alimentation en courant alternatif ou à une autre alimentation dont la tension nominale ne dépasse pas 1 000 V c.a. (efficace) ou 1 000 V c.c. et dont la fréquence nominale ne dépasse pas 100 Hz. Cette quatrième édition annule et remplace la troisième édition publiée en 2005 dont elle constitue une révision technique. Toutes les modifications acceptées peuvent être classées comme des révisions mineures. Le contenu du corrigendum d'avril 2016 a été pris en considération dans cet exemplaire.

FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 14: Sectional specification –
Fixed capacitors for electromagnetic interference

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 60384-14 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 2005. It constitutes a

technical revision. All changes that have been agreed upon can be categorized as minor

revisions.
The text of this standard is based on the following documents:
FDIS Report on voting
40/2199/FDIS 40/2232/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.

A list of all the parts of the IEC 60384 series, published under the general title Fixed

capacitors for use in electronic equipment, can be found on the IEC website.

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 stability 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.
The contents of the corrigendum of April 2016 have been included in this copy.
