IEC 63182-7:2025 ED1

Magnetic powder cores - Guidelines on dimensions and the limits of surface irregularities - Part 7: EER-cores

Apstrakt

IEC 63182-7:2025 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EER-cores made of metallic magnetic powder, the essential dimensions of coil formers to be used with them as well as the effective parameter values to be used in calculations involving them and gives guidelines on allowable limits of surface irregularities applicable to EER-cores.
This document is a specification that is useful in the negotiations between magnetic powder core manufacturers and customers about surface irregularities.
The use of “derived” standards which give more detailed specifications of component parts while still permitting conformance with this document is discussed in Annex A.
