IEC 60384-20:2015 applies to fixed surface mount capacitors for direct current, with metallized electrodes and polyphenylene sulfide dielectric for use in electronic equipment. These capacitors have metallized connecting pads or soldering strips and are intended to be mounted directly onto substrates for hybrid circuits or onto printed boards. They may have "self healing properties" depending on conditions of use and are primarily intended for applications where the a.c. component is small with respect to the rated voltage. This edition includes the following significant technical changes with respect to the previous edition:
a) Revision of the structure in accordance with ISO/IEC Directives, Part 2:2011 (sixth edition) to the extent practicable, and harmonization between other similar kinds of documents.
b) In addition, Clause 4 and all the tables have been reviewed in order to prevent duplications and contradictions.
Condensateurs fixes utilisés dans les équipements électroniques - Partie 20: Spécification intermédiaire - Condensateurs fixes pour montage en surface pour courant continu à diélectrique en film de sulfure de polyphénylène métallisé
L'IEC 60384-20:2015 s'applique aux condensateurs fixes pour montage en surface pour courant continu à électrodes métallisées et à diélectrique en sulfure de polyphénylène destinés aux équipements électroniques. Ces condensateurs sont équipés de contacts de connexion métallisés ou de bandes de brasure et sont destinés à être montés directement sur des substrats pour circuits hybrides ou sur des cartes imprimées. Ils peuvent avoir des propriétés "d'autorégénération" en fonction des conditions d'utilisation et sont principalement destinés à des applications dans lesquelles la composante alternative est petite par rapport à la tension assignée. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) Révision de la structure fondé sur les Directives ISO/IEC, Partie 2:2011 (sixième édition) dans la mesure du possible, et harmonisation avec d'autres types de documents similaires.
b) En outre, révision de l'Article 4 et des tableaux et pour éviter les redondances et les contradictions.

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 60384-20 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.This third edition cancels and replaces the second edition, published in 2008, and constitutes
a technical revision.This edition includes the following significant technical changes with respect to the previous
edition:a) Revision of the structure in accordance with ISO/IEC Directives, Part 2:2011 (sixth edition)
to the extent practicable, and harmonization between other similar kinds of documents.
b) In addition, Clause 4 and all the tables have been reviewed in order to prevent
duplications and contradictions.---------------------- Page: 7 ----------------------

FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 20: Sectional specification – Fixed metallized polyphenylene sulfide
film dielectric surface mount d.c. capacitors
1 General
1.1 Scope
This part of IEC 60384 applies to fixed surface mount capacitors for direct current, with
metallized electrodes and polyphenylene sulfide dielectric for use in electronic equipment.
These capacitors have metallized connecting pads or soldering strips and are intended to be
mounted directly onto substrates for hybrid circuits or onto printed boards. They may have
"self-healing properties" depending on conditions of use and are primarily intended for
applications where the a.c. component is small with respect to the rated voltage.
These capacitors are divided to 3 grades. Performance grade 1 for long life, performance
grade 2 for general purpose and performance grade 3 for miniature type.Capacitors for radio interference suppression are not included, but are covered by
IEC 60384-14.Capacitors used for motor or fluorescent lamp are outside the scope of this standard.
1.2 ObjectThe object of this standard is to prescribe preferred ratings and characteristics and to select
from IEC 60384-1, 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 standard shall
be of equal or higher performance level, lower performance levels are not permitted.
1.3 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including anyamendments) applies.
