23、AL ELECTROTECHNICAL COMMISSION _ THERMISTORS DIRECTLY HEATED POSITIVE STEP-FUNCTION TEMPERATURE COEFFICIENT Part 1-3: Blank detail specification Inrush current application Assessment level EZ FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizat
24、ion 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 end and in addition to other activities, IEC publishes Internatio
25、nal 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 dealt with may participate in t
26、his 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 by agreement between the t
27、wo 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. 3) IEC Publications have t
28、he 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 are used or for any misinte
29、rpretation 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 the corresponding national
30、 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 have the latest edition of
31、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 whatsoever, whether direct or
32、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 publications is indispensable fo
33、r 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 Standard IEC 60738-1-3 has bee
34、n prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This second edition cancels and replaces the first edition issued in 1998. It constitutes a technical revision. This edition contains changes with respect to the referenced subclauses of the revised Generic
35、Specification IEC 60738-1. This publication is to be read in conjunction with IEC 60738-1 60738-1-3 IEC:2008 3 This bilingual version (2014-01) corresponds to the monolingual English version, published in 2008-02. The text of this standard is based on the following documents: FDIS Report on voting 4
36、0/1876/FDIS 40/1893/RVD 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 voted upon. The list of all parts of the IEC 60738 series, under the (new) general title Thermi
37、stors Directly heated positive step-function temperature coefficient, 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 relat
38、ed to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 4 60738-1-3 IEC:2008 INTRODUCTION Blank detail specification A blank detail specification is a supplementary document to the generic specification and contains req
39、uirements for style and layout and minimum content of detail specifications. Detail specifications not complying with these requirements shall not be considered as being in accordance with IEC specifications nor shall they so be described. In the preparation of detail specifications the content of I
40、EC 60738-1:2006,1.4 shall be taken into account. The numbers between brackets on the first page correspond to the following information which shall be inserted in the position indicated. Identification of the detail specification 1 The “International Electrotechnical Commission“ or the National Stan
41、dards Organization under whose authority the detail specification is drafted. 2 The IEC or National Standards number of the detail specification, date of issue and any further information required by the national system. 3 The number and issue number of the IEC or national generic specification. 4 T
42、he IEC number of the blank detail specification. Identification of the thermistor 5 A short description of the type of thermistor. 6 Information on typical construction (if applicable). NOTE When the thermistor is not designed for use on printed boards, this should clearly be stated in the detail sp
43、ecification in this position. 7 Outline drawing with main dimensions which are of importance for interchangeability and/or reference to the national or international documents for outlines. Alternatively, this drawing may be given in an annex to the detail specification. 8 Application or group of ap
44、plications covered and/or assessment level. 9 Reference data on the most important properties, to allow comparison between the various thermistor types. 60738-1-3 IEC:2008 5 1 IEC 60738-1-3-XXX 2 QC 440003 ELECTRONIC COMPONENTS OF ASSESSED IEC 60738-1-3 4 QUALITY IN ACCORDANCE WITH: QC 440003 3 DIRE
