PASSIVE FILTER UNITS FOR ELECTROMAGNETIC
INTERFERENCE SUPPRESSION –

Part 1: Generic specification


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 60939-1 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 2005. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) table 3 has been updated, specifying how to handle the Neutral by 3-phase filter with
Neutral;
b) all details about “Quality assessment” have been deleted in this edition, because this
standard is a safety standard;
c) filters shall be subjected to Test Aa of IEC 60068-2-1 for 16 h, using the degree of severity
of the lower category temperature as prescribed in the relevant specification;

d) since IEC 60068-2-20 does no longer make a difference between Method 1A and 1B, but
only describes Method 1, references to the method to be used are updated.
The text of this standard is based on the following documents:
FDIS Report on voting
40/2046/FDIS 40/2061/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.
A list of all parts of the IEC 60939 series, under the general title Passive filter units for
electromagnetic interference suppression, can be found on the IEC website.
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.

PASSIVE FILTER UNITS FOR ELECTROMAGNETIC
INTERFERENCE SUPPRESSION –

Part 1: Generic specification



1 General
1.1 Scope
This generic specification relates to passive filter units for electromagnetic interference sup-
pression for use within, or associated with, electronic or electrical equipment and machines.
Both single and multi-channel filters within one enclosure are included within the scope of this
generic specification.
Filters constructed of capacitive elements where the inductance is inherent in the construction
of the filter are within the scope of this specification. Similarly, filters constructed of inductive
elements where the capacitance is inherent in the construction of the filter are also within the
scope of this generic specification. The manufacturer should state whether a given component
is to be designed as a capacitor, an inductor or a filter.
The filter units within the scope of this generic specification are further distinguished as those
for which safety tests are appropriate (e.g. those connected to mains supplies) and those for
which such tests are not appropriate. A separate sectional specification covers the passive
filter units for which safety tests are appropriate.
This generic specification establishes standard terms, inspection procedures and methods of
test for use in sectional and detail specifications within the IECQ-CECC system for electronic
components.
1.2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
