Classification of magnetic powder cores

This document specifies classification rules for metallic magnetic powder cores used in
inductive components fulfilling the requirements of the electronics industries.
This document addresses the following objectives for magnetic powder cores suppliers and
users:
– cross-reference between core materials from multiple suppliers;
– assistance to users in understanding the published technical data in catalogues when
comparing multiple suppliers;
– guidance to users in selecting the most applicable core for each application;
– establishing uniform benchmarks for suppliers for performance in the new development of
core material.
The numerical values given in this document are typical values of parameters of the related
material. Direct translation from the material specification into the core specification is not
always easy or possible.
Every detailed material and core specification will be agreed upon between the user and the
supplier.

CLASSIFICATION OF MAGNETIC POWDER CORES
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.

IEC 63299 has been prepared by IEC technical committee 51: Magnetic components, ferrite

and magnetic powder materials. It is an International Standard.
The text of this International Standard is based on the following documents:

97 This International Standard specifies classification rules for metallic magnetic powder cores

98 used in inductive components fulfilling the requirements of the electronics industries.

99 This standard addresses the following purposes for magnetic powder cores suppliers and

100 users:
101 – cross-reference between core materials from multiple suppliers;

102 – assistance to users in understanding the published technical data in catalogues when

103 comparing multiple suppliers;

104 – guidance to users in selecting the most applicable core for each application;

105 – establishing uniform benchmarks for suppliers for performance in new development of

106 core material.

107 The numerical values given in this standard are typical values of parameters of the related

108 material. Direct translation from the material specification into the core specification is not

109 always easy or possible.

110 Every detailed material and core specification should be agreed upon between the user and

111 the supplier.
