IEC 61332 Ed. 4.0 en:2026

Full Description

IEC 61332:2026 This document specifies classification rules for soft ferrite materials used in inductive components (inductors and transformers) fulfilling the requirements of the electronic industries.
This document addresses the following issues for ferrite suppliers and users:
– cross-reference between materials from multiple suppliers;
– assistance to users in understanding the published technical data in catalogues when comparing multiple suppliers;
– guidance to users in selecting the most applicable material for each application;
– setting of nomenclature for IEC standards relating to ferrite;
– establishing uniformed benchmarks for suppliers for performance in new development of materials.
The numerical values given in this document are typical values of the parameters (properties) of the related materials. Direct translation from the material specification into the core specification is not always easy or possible.
Every detailed material and core specification should be agreed upon between suppliers and users.
