Soft ferrite material classification

Specifies classification rules for soft ferrite materials used in inductive components (inductors and transformers) fulfilling the requirements of the electronic industries. Provides cross-reference between materials from multiple suppliers; assistance to customers in understanding the published technical data in catalogues when comparing multiple suppliers; guidance to customers in selecting the most applicable material for each application; nomenclature for IEC standards relating to ferrites.

This European Standard was approved by CENELEC on 2005-10-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in two official versions (English, German). A version in any other language
made by translation under the responsibility of a CENELEC member into its own language and notified to the
Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,

The text of document 51/832/FDIS edition 2 of IEC 61332, prepared by IEC TC 51, Magnetic
components and ferrite materials, was submitted to the IEC-CENELEC parallel vote and was
approved by CENELEC as EN 61332 on 2005-10-01.
This European Standard supersedes EN 61332:1997.
It includes the following significant technical changes with respect to EN 61332:1997.
a) the scope has been reviewed;
b) the column of temperature coefficient of SP class ferrite material has been omitted;
c) the measuring frequency for relative loss factor of SP class has been specified;
d) the parameters of SP class has been coordinated with EN 60401-3.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-07-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-10-01
Annex ZA has been added by CENELEC.
