26、cal 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
27、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 Co
28、mmittee 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
29、 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 a
30、ll 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
31、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 dive
32、rgence 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
33、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 exp
34、erts 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
35、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
36、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 62317-13 has been prepared by technical committee 51: Magnetic components and ferrite materials. This second edition cancels and replaces the f
37、irst edition published in 2008. This edition constitutes a technical revision. This edition includes 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
38、 A minvalues, of main dimensions of coil formers and of gauge dimensions for PQ-cores for PQ 65/54, PQ 78/39 and PQ 107/87. 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 th
39、e approval of this standard can be found in the report on voting indicated in the 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 w
40、ebsite. The committee has decided that the contents of this publication will remain 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 b
41、y a revised edition, or amended. IEC 62317-13:2015 IEC 2015 5 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-pro
42、file PQI-cores made of ferrite, and the locations of their terminal 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 inclusi
43、on in a national standard, or by broad- based use in industry. 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 follo
44、wing documents, in whole or in part, are normatively referenced 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
45、standards 3.1 General Compliance with the following requirements 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 P
46、Q-cores shall be as given in Table 2. See also Figure 1 and Figure 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
47、1 and in Table 2 is permitted. 3.2.2 Effective parameter and A minvalues The effective parameter values for cores having the dimensions given in 3.2.1 are as shown in Table 3 and Table 4. 6 IEC 62317-13:2015 IEC 2015 3.3 Dimensions limits for coil formers The essential dimensions of coil formers sui
48、table for use with a pair of PQ-cores shall 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 thei
49、r sizes and respective weights, it is recommended 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. Figure 1 Dimensions of PQ-cores IEC J L A X X G C E F B D
