IEC 63093-10:2022 pdf download Ferrite cores – Guidelines on dimensions and the limits of surface irregularities – Part 10: PM-cores and associated parts
This part of IEC 63093 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.
