Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 10: PM-cores and associated parts IEC 63093-10:2026 ED2

Publication date:   Feb 6, 2026

Scope

IEC 63093-10:2026 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PM-cores made of magnetic oxides, the main dimensions for coil formers to be used with these cores and the locations of their pins on a modular printed wiring grid in relation to the base outlines of cores. It also specifies the effective parameter values to be used in calculations and gives guidelines on allowable limits of surface irregularities applicable to the PM-cores. The use of derived standards which give more detailed specifications of component parts whilst still permitting compliance with this document is discussed in Annex A.
