IEC 62317-6:2015
Ferrite cores - Dimensions - Part 6: ETD-cores for use in power supplies
IEC 62317-6:2015 specifies the dimensions that are of importance for mechanical interchangeability for ETD-cores made of ferrite, the essential dimensions of coil formers to be used with them, and the effective parameter values to be used in calculations involving them. This first edition cancels and replaces the second edition of IEC 61185 published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:- Changed dimension A of ETD 54 core.

IEC 61185:2005 specifies the dimensions that are of importance for mechanical interchangeability for ETD-cores made of ferrite, the essential dimensions of coil formers to be used with them, and the effective parameter values to be used in calculations involving them.
IEC 63093-6:2018 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ETD-cores made of ferrite and the essential dimensions of coil formers to be used with them, as well the effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to ETD-cores. The specifications contained in this document are useful in negotiations between ferrite core manufacturers and users about surface irregularities. The use of derived standards which give more detailed specifications of component parts while still permitting compliance with this document is discussed in Annex A. This edition includes the following significant technical changes with respect to IEC 62317-6:2015 and IEC 60424-3:2015: a. This document integrates IEC 62317-6:2015 and IEC 60424-3:2015; b. Table 1 ? Allowable areas of chips for ETD-cores, of IEC 60424-3:2015, has been moved to Annex C (informative) of this document.
