The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organization forStandardization (ISO) in accordance with conditions determined by agreement between the two organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60938-2-1 has been prepared by IEC technical committee 40:Capacitors and resistors for electronic equipment.FDISReport on voting40/1112/FDIS40/1138/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.The QC number that appears on the front cover of this publication is the specification numberin the IEC Quality Assessment System for Electronic Components (IECQ).SIST EN 60938-2-1:2002

Detailspecifications not complying with these requirements may not be considered as being inaccordance with IEC specifications nor shall they so be described.In the preparation of detail specifications the content of 1.4 of the sectional specification shallbe taken into account.The numbers between square brackets on the first page of the detail specification correspondto the following information which shall be inserted in the position indicated.Identification of the detail specification[1] The "International Electrotechnical Commission" or the National Standards Organizationunder whose authority the detail specification is drafted.[2] The IEC or National Standards number of the detail specification, date of issue and anyfurther information required by the national system.[3] The number and issue number of the IEC or national generic specification.[4] The IEC number of the blank detail specification.Identification of the inductor[5] A short description of the type of inductor.[6] Information on typical construction (when applicable).[7] Outline drawing with main dimensions which are of importance for interchangeabilityand/or reference to the national or international documents for outlines. Alternatively, thisdrawing may be given in an annex to the detail specification.[8] Application or group of applications covered and/or assessment level.[9] Reference data on the most important properties, to allow comparison between thevarious inductor types.SIST EN 60938-2-1:2002
