FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –
Part 9: Sectional specification:
Fixed capacitors of ceramic dielectric, Class 2
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60384-9 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 1988 and amendment 1
(2000). This third edition is a result of maintenance activities related to the previous edition.
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

2 Preferred ratings and characteristics
2.1 Preferred characteristics
The values given in detail specifications shall preferably be selected from the following:
2.1.1 Preferred climatic categories
The capacitors covered by this specification are classified into climatic categories according
to the general rules given in IEC 60068-1.
The lower and upper category temperatures and the duration of the damp heat, steady state
test shall be chosen from the following:
Lower category temperature: –55 °C, –40 °C, –25 °C and –10 °C
Upper category temperature: +70 °C, +85 °C, +100 °C and +125 °C
Duration of the damp heat, steady state test: 4, 10, 21 and 56 days
The severities for the cold and dry heat tests are the lower and upper category temperatures
respectively.
2.2 Preferred values of ratings
2.2.1 Rated temperature
For capacitors covered by this specification, the rated temperature is equal to the upper
category temperature.
2.2.2 Rated voltage (U )
R
The preferred values of rated voltage are: 25 – 40 – 63 – 100 – 160 – 250 – 400 – 630 – 1000
– 1 600 – 2 500 and 4 000 V. These values conform to the basic series of preferred values R5
given in ISO 3. If other values are needed they shall be chosen from the R10 series.
2.2.3 Category voltage (U )
C
Since the rated temperature is defined as the upper category temperature, the category
voltage is equal to the rated voltage, as defined in IEC 60384-1, 2.2.17.
2.2.4 Preferred values of rated capacitance and associated tolerance values
2.2.4.1 Preferred values of rated capacitance

Table 2 denotes with a cross the preferred values of temperature characteristics with and
without d.c. voltage applied. The method of coding the subclass is also given; for example a
dielectric with a percentage change of ±20 % without d.c. voltage applied over the
temperature range from -55 °C to +125 °C, will be defined as a dielectric of Class 2C1.

dielectric to form the electrode; for multilayer capacitors it is the first common firing of the
dielectric-electrode assembly.
3.2 Structurally similar components
Capacitors, considered as being structurally similar, are capacitors produced with similar
processes and materials, though they may be of different case sizes and values.
3.3 Certified records of released lots

detail specification and when requested by a purchaser. After the
