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.

1.4.4 Marking
The detail specification shall specify the content of the marking on the capacitor and on the
package. Deviations from 1.6 of this sectional specification shall be specifically stated.
1.5 Terms and definitions
For the purposes of this sectional specification, the terms and definitions given in
IEC 60384-1, as well as the following apply.
1.5.1
surface mount capacitor
a capacitor whose small dimensions and nature or shape of terminations make it suitable for
surface mounting in hybrid circuits and on printed boards
1.5.2
fixed capacitors, ceramic dielectric, Class 1
a capacitor specially designed and suited for resonant circuit application where low losses
and high stability of capacitance are essential or where a precisely defined temperature
coefficient is required, for example for compensating temperature effects in the circuit.
The ceramic dielectric is defined by its rated temperature coefficient (α)
1.5.3
subclass
for a given rated temperature coefficient, the subclass is defined by the rated tolerance on the
temperature coefficient (see Table 2)
NOTE The rated temperature coefficient value and its tolerance refer to the temperature interval of +20 °C to
+85 °C, but because in practice TC curves are not strictly linear, it is necessary to define limiting capacitance
deviation (∆C/C) for other temperatures (see Table 3)
1.5.4
category temperature range
range of ambient temperatures for which the capacitor has been designed to operate
continuously; this is given by the lower and upper category temperature
1.5.5
rated temperature
maximum ambient temperature at which the rated voltage may be continuously applied
1.5.6
rated voltage (d.c.)
U
R
maximum direct voltage or peak value of pulse voltage which may be applied continuously to
a capacitor at any temperature between the lower category temperature and the rated
temperature
NOTE The sum of the d.c. voltage and the peak a.c. voltage or the peak to peak a.c. voltage, whichever is the
greater, applied to the capacitor shall not exceed the rated voltage. The value of the peak a.c. voltage shall not
exceed the value determined by the permissible reactive power.
1.5.7
category voltage
U
C
maximum voltage which may be applied continuously to a capacitor at its upper category
temperature

1.6 Marking
See 2.4 of IEC 60384-1with the following details:
1.6.1 The information given in the marking is normally selected from the following list; the
relative importance of each item is indicated by its position in the list:
a) rated capacitance;
b) rated voltage (d.c. voltage may be indicated by the symbol     or     );
c) tolerance on rated capacitance;
d) temperature coefficient and its tolerance as applicable ( according to 2.2.5);
e) year and month (or week) of manufacture;
f) manufacturer’s name or trade mark;
g) climatic category;
h) manufacturer’s type designation;
i) reference to the detail specification.
1.6.2 These capacitors are generally not marked on the body. If some marking can be
applied, they shall be clearly marked with as many as possible of the above items as is
considered useful. Any duplication of information in the marking on the capacitor should be
avoided.
1.6.3 Any marking shall be legible and not easily smeared or removed by rubbing with the
finger.
1.6.4 The package containing the capacitor(s) shall be clearly marked with all the
information listed in 1.6.1.
1.6.5 Any additional marking shall be so applied that no confusion can arise.
2 Preferred rating and characteristics
2.1 Preferred characteristics
The values given in the detail specification shall preferably be selected from the following:
2.1.1 Preferred climatic categories
The capacitors covered by this sectional 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, –10 °C and +10 °C
Upper category temperature: +70 °C, +85 °C, +100 °C, +125 °C and +150 °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.
NOTE The resistance to humidity resulting from the above climatic category is for the capacitors in their
unmounted state. The climatic performance of the capacitors after mounting is greatly influenced by the mounting
substrate, the mounting method (see 4.3) and the final coating.
