The object of the IEC is to promote internationalcooperation on all questions concerning standardization in the electrical and electronic fields. To this end and inaddition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technicalcommittees; any IEC National Committee 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 thispreparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordancewith 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 an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from all interestedNational Committees.3)The documents produced have the form of recommendations for international use and are published in the form ofstandards, technical reports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC International Standardstransparently to the maximum extent possible in their national and regional standards. Any divergence between the IECStandard and the corresponding national or regional standard shall be clearly indicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipmentdeclared 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 subject ofpatent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 1797-1 has been prepared by IEC technical committee 51: Magneticcomponents and ferrite materials.The text of this standard is based on the following documents:FDISReport on voting

1797-1 ©I EC:1996- 7 -TRANSFORMERS AND INDUCTORS FOR USEIN TELECOMMUNICATION AND ELECTRONIC EQUIPMENT -MAIN DIMENSIONS OF COIL FORMERS -Part 1: Coil formers for laminated cores1 Scope and objectThis part of IEC 1797 specifies the main dimensions of coil formers for transformers and inductors,using a square stack of the laminations inserted in the coil formers. The main dimensions arethose permitting interchangeability with respect to conformance with core sizes and outline dimen-sions of the completed components.2 Normative referencesThe following normative documents contain provisions which, through reference in this text,constitute provisions of this part of IEC 1797. At the time of publication, the editions indicated werevalid. All normative documents are subject to revision, and parties to agreements based on thispart of IEC 1797 are encouraged to investigate the possibility of applying the most recent editionsof the normative documents indicated below. Members of IEC and ISO maintain registers ofcurrently valid International Standards.IEC 68-2-20: 1979, Basic environmental testing procedures - Part 2: Tests - Test T: SolderingAmendment 2 (1987)IEC 321: 1970, Guidance for the design and use of components intended for mounting on boardswith printed wiring and printed circuitsAmendment 1 (1975)IEC 707: 1981, Methods of test for the determination of the flammability of solid electricalinsulating materials when exposed to an igniting sourceAmendment 1 (1992)IEC 740: 1982, Laminations for transformers and inductors for use in telecommunication andelectronic equipmentAmendment 1 (1991)IEC 852: Outline dimensions of transformers and inductors for use in telecommunication andelectronic equipmentISO 3: 1973, Preferred numbers - Series of preferred numbersISO 286-1: 1988, ISO system of limits and fits - Part 1: Bases of tolerances, deviations and fits3 LaminationsFor the purpose of this specification, the laminations shall conform with the dimensions of IECtypes YEI 1, YEx 2, YUI 1, YUI 2 and YM 1, as prescribed in the tables of IEC 740.

The coil former designmay not correspond to the graphic representation shown in the figures, but the principaldimensions which have tolerances shall be followed and other details such as intermediateflanges, etc. may be arranged between the manufacturer and the user.All the listed dimensions in this standard are in millimetres.SIST EN 61797-1:2002
1797-1 ©IEC:1996– 11 –Tolerances of coil formers, except where indicated as maximum or minimum, shall complywith ISO 286-1. The appropriate tolerances are shown at the head of each column of the table ofdimensions. Flange thickness should be 0,4 mm minimum.Length of terminal pins depends on printed wiring board thickness of 1,5 mm or 1,6 mm.5.2 Dimensions corresponding to the core stack heightIn the associated standards on outline dimensions of transformers and inductors, IEC 852 series,a range of stack heights is specified, which allows continuous variations of power ratings, althoughthe square stack is preferred. The increment of the stack height follows the R10 series of preferrednumbers)* as a multiple of the width of that limb of the lamination which carries the total magneticflux. A suffix letter is used to designate the appropriate stack height as shown below:Suffix letter zMultiple of limb width of laminationa0,5b0,63c0,8d1,0square stacke1,25f1,6g2,0If a stack height other than the preferred square stack is used for the core, and one of the otherspecified stack heights is chosen, the dimensions of the associated coil formers in the direction ofthe stack height will differ from those given in the following tables, which apply to square stacksonly.In this case the values of dimensions c and h are obtained by increasing or decreasing the valuesin the appropriate tables by the same amount as the stack height changes.The lamination designation followed by the appropriate suffix letter shall be used to designate thecore. If two larger parts of a lamination shape are used to form a core, this shall be indicated bythe letter L to the designation (e.g. YEx 2).As defined in ISO 3.SIST EN 61797-1:2002
