FERRITE CORES – STANDARD INDUCTANCE
FACTOR FOR GAPPED CORES AND ITS TOLERANCE
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.

International Standard IEC 62358 has been prepared by IEC technical committee 51:

Magnetic components and ferrite materials.

This second edition cancels and replaces the first edition published in 2004. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

editions:
a) addition of A value (inductance factor) and its tolerance for PQ-cores;
b) addition of A value (inductance factor) and its tolerance for EFD-cores;

c) addition of A value (inductance factor) and its tolerance for Low-profile ER-I-cores;

d) addition of A value (inductance factor) and its tolerance for Low-profile ER-cores

(ER9,5 × 2,5 × 5, ER11 × 2,5 × 6, ER14,5 × 3 × 7 ferrite cores are same as the previous

edition);

e) addition of A value (inductance factor) and its tolerance for Low-profile PQ-I-cores.

INTRODUCTION

The A value (inductance factor) and its tolerance have been specified by the users before.

When manufacturers wish to have an inventory for short delivery, they have to hold the

products before gapping since there is no standard for the A value. Because of electronic

commerce and the increased demand for rapid delivery of products, it will be more convenient

for customer
