18、l specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning st
19、andardization 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 prepar
20、ation 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 w
21、ith 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 su
22、bjects 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 technic
23、al 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
24、 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
25、equipment declared to be in conformity with an IEC Publication. 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 a
26、nd 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)
27、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 right
28、s. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62317-1 has been prepared IEC technical committee 51: Magnetic components and ferrite materials. This bilingual version (2013-05) corresponds to the monolingual English version, published i
29、n 2007-07. The text of this standard is based on the following documents: CDV Report on voting 51/874/CDV 51/890/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been vo
30、ted upon. 62317-1 IEC:2007 3 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 62317 series, published under the general title Ferrite cores Dimensions, can be found on the IEC website. The committee has decided that the contents of this
31、publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 4 62317-1 IEC:2007
32、 FERRITE CORES DIMENSIONS Part 1: General specification 1 Scope This part of IEC 62317 specifies the standards and existing projects dealing with dimensions of ferrite cores. It is intended that this standard will include ferrite cores which are widely used and referenced in industry, either because
33、 they are included in national standards, or because they are seen to have broad-based use in industry. Where applicable, it is intended that the existing industrial name for each standard part should appear with the part within this series. It is intended that this standard will exclude ferrite cor
34、es which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded. Examples: E24/25 (USA) and E24,5 (Metric) are two similar parts, yet they are included separately in this series because they are national standards, widely used. E
35、-187 (USA) and FEE19A (Japan) are two similar parts, yet they are included separately in this series because they are national standards, widely used. EP5 has small dimensional differences when comparing different manufacturers, yet only one EP5 is shown in this series, because they are only minor v
36、ariations on the single basic part. A ferrite core produced by only one or two suppliers may generally be considered a specialty part, and not suitable as a standard core within this series. A ferrite core produced by three or more competing manufacturers may generally be considered to be a candidat
37、e to be included in this series. IEC publishes electrical standards for families of ferrite cores, as well as this series of dimensional standards for families of ferrite cores. Modifications to the ferrite cores listed in one type of standard should be reflected in the other type. 2 Normative refer
38、ences The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60133, Dimensions of pot-cores made of
39、magnetic oxides and associated parts IEC 60647, Dimensions for magnetic oxide cores intended for use in power supplies (EC- cores) IEC 61185, Ferrite cores (ETD-cores) intended for use in power supply applications Dimensions 62317-1 IEC:2007 5 IEC 61247, PM-cores made of magnetic oxides and associat

42、to be included within the IEC 62317 series include existing standards, future standards already in development, and future standards that may be developed later. The new references should be recorded on the IEC web site as follows: a) for existing projects: the new project numbers should be recorded
43、 on the IEC web site at the time of circulation of next working drafts, with an explanatory note on the cover sheet; b) for existing publications: the publication numbers should be updated at the time of each new revision of these standards. An explanatory note should be included in the foreword of
44、future publications; c) for future new projects, the new project numbers should be selected to be consistent with the IEC 62317 series. A table showing existing project (or publication) references and the proposed new project (or publication) references is given in Table A.1. 4 Dimension description
45、s Table 1 and Table 2 describe the alphabetic character assignments for the major dimensions of ferrite shapes. All other minor core dimension designations are left to the discretion of the specifier. Table 1 Toroid core dimension designations Letter Dimension description A Toroid outside diameter B

48、 and functions of core parts and surfaces (see Figure 1) 5.1 Mating surfaces These surfaces are generally ground in order to reduce the residual air gap between the two core halves. Consequently, irregularities on these surfaces shall be considered as major ones, and carefully evaluated with regard
49、to their influence on the magnetic properties of the complete circuit. 5.2 Centre post This should be considered as the most important part of the core due to its function of carrying the total flux generated by the winding. The centre post of ferrite cores is generally circular (with or without a hole) or rectangular. 5.3 Outer walls or legs The main function of the outer walls (e.g. pot-cores) or the outer legs
