27、 ELECTROTECHNICAL COMMISSION _ HIGH FREQUENCY INDUCTIVE COMPONENTS NON-ELECTRICAL CHARACTERISTICS AND MEASURING METHODS Part 1: Fixed, surface mounted inductors for use in electronic and telecommunication equipment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organi

28、zation 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 standardization in the electrical and electronic fields. To this end and in addition to other activitie

29、s, 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 Committee interested in the subject deal

30、t 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 accordance with conditions determined

31、 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 all interested IEC National Committees.

32、 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 responsible for the way in which they

33、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 divergence between any IEC Publication and

34、 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 equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they

35、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, property damage or other damage of any nature wha

36、tsoever, 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 in this publication. Use of the referenced publi

37、cations 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 any or all such patent rights. International Sta

38、ndard IEC 62025-1 has been prepared by IEC technical committee 51: Magnetic components and ferrite materials. This second edition cancels and replaces the first edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes

39、 with respect to the previous edition: nomenclature of dimensions in Figure 1 has been changed; a new Table 1, Letter code for inductance values, has been added; dimensions for shapes in Table 2 and Table 5 have been added; new operating temperature ratings in Table 9 have been added. 4 62025-1 IEC:

40、2007 This bilingual version (2014-01) corresponds to the monolingual English version, published in 2007-05. The text of this standard is based on the following documents: FDIS Report on voting 51/883/FDIS 51/889/RVD Full information on the voting for the approval of this standard can be found in the

41、 report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 62025 series, published under the general title High frequency inductive co

42、mponents Non-electrical characteristics and measuring methods, can be found on the IEC website. The committee has decided that the contents of this 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 t

43、he specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 62025-1 IEC:2007 5 HIGH FREQUENCY INDUCTIVE COMPONENTS NON-ELECTRICAL CHARACTERISTICS AND MEASURING METHODS Part 1: Fixed, surface mounted inductors for use in electronic

44、 and telecommunication equipment 1 Scope and object This part of IEC 62025 applies to fixed, surface mounted inductors and ferrite beads. Should conflict arise between these specifications and the detail specifications, the latter will take precedence. The object of this standard is to establish req

45、uirements for fixed, surface mounted inductors, to describe terms, to give recommendations for standard values and dimensions and to give guidance on fixed, surface mounted inductors. 2 Normative references The following referenced documents are indispensable for the application of this document. Fo

46、r dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 61605: 2005, Fixed inductors for use in electronic and telecommunication equipment- Marking codes 3 Graphical symbols and designations 3.1

47、 Designation Designation of the fixed, surface mounted inductors is expressed by 12 digits. Designation of ferrite beads shall be specified in the detail specifications. a) b) c) d) e) a) Identification of the type of inductor: fixed, surface mounted inductors shall be identified by the three alphab

48、etic characters LCL. b) Indication of outline dimensions: the outline dimensions of the surface mounted inductor shall be indicated by a four-digit number based on two significant figures for each dimension of L and W (or H). As for the dimensions of shape D, the first two digits indicate the longer

49、 side dimension L, and the last two digits indicate the shorter side dimension W, as shown in Figure 1. As for the dimensions of shape K, the first two digits indicate the outline dimension L, and the last two digits indicate the height dimension H. c) Indication of shape: a single alphabetic character as given in Figure 1 indicates the shape for fixed, surface mounted inductors.
