Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 12: Ring-cores IEC 63093-12:2019 ED1

Publication date:   Apr 4, 2019

Scope

IEC 63093-12:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ring-cores, also called toroid cores, and the effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to ring-cores. This document is a specification useful in the negotiations between ferrite core manufacturers and users about surface irregularities.
This first edition cancels and replaces the first edition of IEC 62317-12 published in 2016 and the second edition of IEC 60424-4 published in 2015. This edition constitutes a technical revision.
IEC 63093-12 integrates the contents of IEC 62317-12:2016 and IEC 60424-4:2015.
