20、ical 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

21、 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 C

22、ommittee 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

23、 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

24、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

25、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

26、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

27、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

28、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

29、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

30、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 62317-12 has been prepared IEC technical committee 51: Magnetic components, ferrite and magnetic powder materials. This first edition cancels a

31、nd replaces the first edition of IEC TR 61604 published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TR 61604: a) amendment of Clause 5 concerning the relationship between standard of European, Japanese

32、and U.S.A. sizes; b) addition of Subclause 5.3 concerning coating. BS EN 62317-12:2016 4 IEC 62317-12:2016 IEC 2016 The text of this standard is based on the following documents: CDV Report on voting 51/1128/CDV 51/1143/RVC Full information on the voting for the approval of this International Standa

33、rd can be found in the report on voting indicated in the above table. This document 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 de

34、cided 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. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bil

36、g-cores, also called toroid cores, and the effective parameter values to be used in calculations involving them. The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, meaning that they are in broad-based use within industry.

37、 See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. 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.

41、2317-12:2016 IEC 2016 Table 1 Ring core dimension designations Letter Dimension description A Outside diameter B Inside diameter C Height 5.2.2 Identification of standard sizes Table 2 shows the nominal dimensions for the range of standard ring cores. Table 2 also shows, where applicable, the origin

42、 and regional name of each standard size, whether from historical European sizes, historical Japanese sizes, or historical USA sizes. The previous IEC Technical Report, 61604, detailed the different ring sizes that were tooled and commonly used in the three distinct geographic regions. IEC TR 61604

43、laid the groundwork for the present standard, which reflects the more global nature of the industry, compared with the time when ferrite standards were evolving in different parts of the world. Manufacturers tend to have more globally complete offerings of ring sizes than before, leading to a profus

44、ion of different sizes. The number of different ring sizes used in total is quite large, far in excess of the 82 commonly known standard sizes shown here, for a couple of reasons: ring cores are relatively inexpensive to build tooling for, nor does a new ring core require an expensive new coil forme

45、r to be tooled up, meaning that custom ring cores are often commercially practical. Ferrite rings, lacking a residual air gap, such as E-cores and other shapes have at their mating surfaces, exhibit directly the full magnetic performance possible in the ferrite material, meaning that tooling up prec

46、isely optimal new dimensions can give a significant advantage to a designer who is optimizing for best possible performance. 5.2.3 Effective parameter values The effective parameter values for the standard ring cores are given in Table 3. For global practicality and simplicity, the effective paramet

47、ers in this document are calculated from the nominal dimensions assuming cores of rectangular cross section, and are useful for reference and comparison of cores. For cores having a cross section with an appreciable average rounding radius, more precise values can be calculated from the method given

48、 in IEC 60205, if required. 5.2.4 Dimensional limits for standard sizes The standard tolerance limits for uncoated ring cores are given in Table 4. Manufacturers may choose to offer looser standard limits for ferrite materials that exhibit greater process variability, or tighter limits for applicati

49、ons that justify higher processing and yield costs to achieve narrower dimensional range. The limits take account of shrinkage variation and warping during firing. The specification for out-of-round condition of the inner or outer circumference is that the inside diameter (ID) and outside diameter (OD) must stay within the indicated limits, measured at any point. Similarly, the specification for non-flat condition of the sides of a ring is that the height minimum and maximum must be ac
