Fixed inductors for electromagnetic interference suppression - Part 1: Generic specification
IEC 60938-1:2021 applies to inductors designed for electromagnetic interference suppression intended for use within all kind of electric and electronic equipment.In this generic specification, normative references and terms and definitions are given. It also prescribes general requirements and the suitable test and measurement procedures for interference suppression inductors. Annex B states special requirements for earth inductors.This edition includes the following significant technical changes with respect to the previous edition:a) material tests added;b) improved readability and clear separation between test descriptions in the generic spec and requirements in the sectional specification;c) creepage and clearance requirements are now defined in sectional specifications only;d) AC testing for voltage test included.
