20、otechnical 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 Specifica
21、tions, 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. Internationa
22、l, 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 dec
23、isions 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 inte
24、rnational 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 o
25、rder 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 c
26、learly 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 certificatio
27、n 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, pr
28、operty 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 i
29、n 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 a
30、ny or all such patent rights. International Standard IEC 62317-13 has been prepared by technical committee 51: Magnetic components and ferrite materials. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes
31、 the following significant technical changes with respect to the previous edition: a) addition of three core sizes (PQ 65/54, PQ 78/39 and PQ 107/87) in Table 1, b) addition of effective parameter and Aminvalues, of main dimensions of coil formers and of gauge dimensions for PQ-cores for PQ 65/54, P
32、Q 78/39 and PQ 107/87. BS EN 62317-13:2015 4 IEC 62317-13:2015 IEC 2015 The text of this standard is based on the following documents: FDIS Report on voting 51/1095/FDIS 51/1104/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the
33、 above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 62317 series, under the general title Ferrite cores Dimensions, can be found on the IEC website. The committee has decided that the contents of this publication will rema
34、in unchanged until the stability 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. BS EN 62317-13:2015IEC 62317-13:2015 IEC 2015 5
35、FERRITE CORES DIMENSIONS Part 13: PQ-cores for use in power supply applications 1 Scope This part of IEC 62317 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PQ-cores and low-profile PQI-cores made of ferrite, and the locations of their ter
36、minal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. The selection of core sizes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry.
37、NOTE See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. The general considerations that the design of this range of cores is based upon are given in Annex A. 2 Normative references The following documents, in whole or in part, are normatively referenced
38、 in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Void. 3 Primary standards 3.1 General Compliance with the following requirement
39、s ensures mechanical interchangeability of complete assemblies and wound coil formers. 3.2 Dimensions of PQ-cores 3.2.1 Principal dimensions The principal dimensions of PQ-cores shall be as given in Table 1 and those of the low-profile PQ-cores shall be as given in Table 2. See also Figure 1 and Fig
40、ure 2. The dimensions of the cores may be checked by means of gauges. By way of example, a possible standard for these gauges is given in Annex B, although no relaxation of the requirements for the dimensions of the cores given in Table 1 and in Table 2 is permitted. 3.2.2 Effective parameter and Am
41、invalues The effective parameter values for cores having the dimensions given in 3.2.1 are as shown in Table 3 and Table 4. BS EN 62317-13:2015 6 IEC 62317-13:2015 IEC 2015 3.3 Dimensions limits for coil formers The essential dimensions of coil formers suitable for use with a pair of PQ-cores shall
42、be as given in Table 5. See also Figure 3. 3.4 Pin locations and base outlines These shall be as shown in Figure 4. 3.5 Pin diameter Coil former terminations (pins) shall be accepted by a gauge having 1,2 mm holes on a true position. 4 Mounting Due to their sizes and respective weights, it is recomm
43、ended that the cores above PQ 35/35 (including PQ 35/35) be fixed on the printed board with mounting assemblies at two opposite sides of their coil formers. Concerning low-profile PQ-cores, no mounting assemblies are defined. It is recommended that the two cores be fixed by glue or adhesive tape. Fi
