20、 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 th
21、e 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
22、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 Internationa
23、l 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 te
24、chnical 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 Pu
25、blications 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 n
26、ational 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
27、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,
28、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 publi
29、cation, 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 possibi
30、lity 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 61332 has been prepared IEC technical committee 51: Magnetic components, ferrite and magnetic powder
31、 materials. This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision. 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
32、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 f“ and “power loss density“ have also been changed; d) changed “B“ of PW4 class from 50 mT to 100 mT; “B f“ and “power loss density“ have also been ch
33、anged. BS EN 61332:2017 4 IEC 61332:2016 IEC 2016 The text of this standard is based on the following documents: FDIS Report on voting 51/1146/FDIS 51/1155/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above t
34、able. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document.
35、 At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. BS EN 61332:2017IEC 61332:2016 IEC 2016 5 SOFT FERRITE MATERIAL CLASSIFICATION 1 Scope This document specifies classification
36、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
37、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
38、for performance in new development of materials. The numerical values given in this document are typical values of the parameters (properties) of the related materials. Direct translation from the material specification into the core specification is not always easy or possible. Every detailed mater
39、ial and core specification should be agreed upon between the user and the manufacturer. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited a
40、pplies. For undated references, the latest edition of the referenced document (including any amendments) applies.

41、ns given in IEC 60050-221 apply.

42、on Soft ferrite materials may be classified according to the following basic parameters: BS EN 61332:2017 6 IEC 61332:2016 IEC 2016 initial permeability and relevant operation frequency and/or applicable maximum frequency; initial permeability as a function of the temperature; applicable maximum flu
43、x density and/or amplitude permeability; power loss at a given frequency, temperature and flux density; normalized impedance at a given frequency. 4.2 Main classes Soft ferrite materials may be divided into three main classes identified by two letters as follows: class IS materials are for use at AC
44、 low flux density as impedances in interference suppression (EMI) applications; class SP materials are for use at low flux density in signal processing applications; class PW materials are for use at high flux density (power application). 4.3 Subclasses Each main class is divided into subclasses ide
45、ntified by two letters and a serial number. Ferrite manufacturers catalogues may indicate more than one class into which a material grade can fall, where desired. 5 Soft ferrite material classes 5.1 Materials used as impedances in interference suppression applications (IS class) These materials are
46、mainly used in the shape of rods, tubes, beads, wide band chokes, bobbin cores and rings. The relevant subclasses are given in Table 1.
