FIXED CAPACITORS FOR USE IN ELECTRONIC EQUIPMENT –

Part 8: Sectional specification –
Fixed capacitors of ceramic dielectric, Class 1

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 60384-8:2015. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in
strikethrough red text.
IEC 60384-8 has been prepared by IEC technical committee 40: Capacitors and resistors for
electronic equipment. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The document has been completely restructured to comply with ISO/IEC Directives, Part 2
and to make it more useable; tables, figures and references have been revised accordingly.
Annex X contains all cross-references of changes in clause/subclause numbers.
b) The terms have been replaced by the letter symbols in Table 3.
c) Code of temperature coefficient and tolerance of C0G, U2J have been added in Table 4,
Table 6, Table 8, Table 9, Table 11, Table 13, Table 16 and Annex B.
d) Annex B has been changed from informative to normative.
e) Clause C.5 (Test schedule for quality conformance inspection) has been newly added to
withdraw the blank detail specification: IEC 60384-8-1.
The text of this International Standard is based on the following documents:

3.1
fixed capacitors, capacitor of ceramic dielectric, Class 1
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
Note 1 to entry: The ceramic dielectric is defined by its nominal temperature coefficient (α).
3.2
subclass
for a given nominal temperature coefficient ; it is defined by the tolerance on the temperature
coefficient (see Table 2) tolerance on the temperature coefficient for a given nominal
temperature coefficient (see Table 2)
Note 1 to entry: The nominal temperature coefficient value and its tolerance refer to the temperature interval of
+20 °C or +25 °C to +85 °C but because in practice TC curves are not strictly linear, it is necessary to define limiting
capacitance deviations (∆C/C) for other temperatures (see Table 3 and Annex B). The same information is expressed
in graphical form in Figure A.1 to Figure A.15.
Figure A.1 to Figure A.15 enable the user to form an estimate of the value and tolerance of 1/C × (dC/dT) , the
T
incremental temperature coefficient at a given temperature T, though this quantity is not required specifically to be
measured in the test.
3.3
rated voltage
U
R
maximum DC voltage that may can be applied continuously to the terminations of a capacitor
at the rated temperature
Note 1 to entry: Maximum DC voltage is the sum of the DC voltage and peak AC voltage or peak pulse voltage
applied to the capacitor.

given in ISO 3. If other values are needed, they shall be chosen from the R10 series.
The sum of the DC voltage and the peak AC voltage applied to the capacitor should shall not
exceed the rated voltage. The value of the peak alternating voltage should not exceed the value
determined by the permissible reactive power.
4.2.3 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 60384-1:20082021, 3.5.
4.2.4 Preferred values of nominal capacitance and associated tolerance values

Those temperature coefficient values are not subject to inspection, since no limits for relative capacitance
variation are specified in Table 3.

4.2.5.2 Limits of Permissible relative variation of capacitance
Table 3 shows for each combination of temperature coefficient and tolerance the permissible
relative variation of capacitance expressed in parts per thousand at both the upper and lower
category temperatures. Temperature coefficients and tolerances are expressed in parts per
−6
million per Kelvin (10 /K). In the case of reference temperature 25 °C, see Table B.1 for an
explanation of the permissible relative variation of capacitance.
Figure A.1 to Figure A.15 show the limits of variation of capacitance with temperature for the
temperature coefficients and subclasses listed in Table 3.
