Soft ferrite material classification

IEC 61332:2016(E) specifies classification rules for soft ferrite materials used in inductive components (inductors and transformers) fulfilling the requirements of the electronic industries. This document addresses the following issues for ferrite suppliers and users: - 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; - setting of nomenclature for IEC standards relating to ferrite; - establishing uniform benchmarks for suppliers for performance in new development of materials. This edition includes the following significant technical changes with respect to the previous edition: a) deleted "c" rank from subclass from Table 3, because of too large power loss density; b) added "a-wide" rank in subclasses PW3, PW4 and PW5 in Table 3; c) changed "B" of PW3 class from 100 mT to 200 mT; "B x f" and "power loss density" have also been changed; d) changed "B" of PW4 class from 50 mT to 100 mT; "B x f" and "power loss density" have also been changed.

Classification des matériaux ferrites doux

L'IEC 61332:2016 spécifie les règles de classification pour les matériaux ferrites doux utilisés dans les composants inductifs (inductances et transformateurs) qui satisfont aux exigences des domaines de l’électronique. Le présent document traite des points suivants pour les fournisseurs et les utilisateurs de ferrite: - références croisées entre matériaux issus de plusieurs fournisseurs; - aide apportée aux clients pour comprendre les données techniques publiées dans les catalogues lors de la comparaison de plusieurs fournisseurs; - recommandations aux clients pour le choix du matériau le plus approprié pour chaque application; - établissement d'une nomenclature pour les normes IEC en rapport avec la ferrite; - établissement de références uniformes pour les fournisseurs sur la performance du nouveau développement de matériaux. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) rang "c" supprimé de la sous-classe du Tableau 3 à cause d'une densité de perte de puissance trop importante; b) rang "a-large" ajouté dans les sous-classes PW3, PW4 et PW5 dans le Tableau 3; c) "B" de la classe PW3 modifié de 100 mT à 200 mT; "B ´ f" et "densité de perte de puissance" ont également été modifiés; d) "B" de la classe PW4 modifié de 50 mT à 100 mT; "B ´ f" et "densité de perte de puissance" ont également été modifiés.

Klasifikacija mehkoferitnih materialov

Ta dokument določa pravila za klasifikacijo mehkoferitnih materialov, ki se uporabljajo v indukcijskih sestavnih delih (dušilke in transformatorji) ter izpolnjujejo zahteve industrije elektronske opreme.
Ta dokument obravnava naslednja vprašanja za dobavitelje in uporabnike feritov:
• navzkrižno sklicevanje med materiali več dobaviteljev;
• pomoč strankam pri razumevanju objavljenih tehničnih podatkov v katalogih med
primerjavo več dobaviteljev;
• smernice za stranke pri izbiri najprimernejšega materiala za posamezen primer uporabe;
• določitev poimenovanja za standarde IEC v zvezi s feritom;
• določitev enotnih meril za učinkovitost dobaviteljev pri razvoju novih materialov.
Številske vrednosti, podane v tem dokumentu, so tipične vrednosti parametrov (lastnosti) povezanih materialov. Neposreden prevod iz specifikacije materiala v osnovno specifikacijo ni vedno preprost ali mogoč.
Uporabnik in proizvajalec se morata dogovoriti o uporabi vsake podrobne specifikacije materiala in osnovne specifikacije.

SOFT FERRITE MATERIAL CLASSIFICATION
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.
