FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60133 has been prepared by technical committee 51: Magnetic
components and ferrite materials.
This edition cancels and replaces the third edition published in 1985, and constitutes a
technical revision.
This bilingual version (2001-09) replaces the English version.
The text of this standard is based on the following documents:
FDIS Report on voting
51/570/FDIS 51/580/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.
Annexes A, B and C are given for information only.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged
until 2004. At this date, the publication will be
reconfirmed;
withdrawn;
replaced by a revised edition, or
amended.

DIMENSIONS OF POT-CORES MADE OF MAGNETIC OXIDES
AND ASSOCIATED PARTS
1 Scope
This International Standard specifies the dimensions that are of importance for mechanical
interchangeability for a preferred range of pot-cores made of magnetic oxides, and the
dimensional limits for coil formers to be used with them. The general considerations upon
which the design of this range of cores is based are given in annex A.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
IEC 60205, Calculation of effective parameters of magnetic piece parts
3 Primary standards
Compliance with the following requirements ensures mechanical interchangeability of complete
assemblies and coil formers.
3.1 Dimensions of pot-cores
3.1.1 Principal dimensions
The principal dimensions of pot-cores shall be as given in table 1.
