International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 62317-2:2010
Title Ferrite cores - Dimensions - Part 2: Pot-cores for use in telecommunications, power supply, and filter applications
Project Number 22401
Abstract/Scope IEC 62317-2:2010 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of pot-cores made of ferrite, and the dimensional limits for coil formers to be used with them. The selection of core sizes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. This first edition cancels and replaces the fourth edition of IEC 60133 published in 2000. The main changes with respect to the previous edition of IEC 60133 are listed below: - changed 'e dimension' of P4,6/3,1 in Table 6 from 3,20 Max. to 3,40 Max.; - removed 'derived standards' from Annex B (informative) in the fourth edition of IEC 60133; - changed the name of core parts in Subclause 3.1.2 from 'Grooves' to 'Wire-ways' in accordance with IEC 62317-1 Subclause 5.6.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
