What is BS EN 61332 - Soft ferrite material classification about?
BS EN 61332 is a European standard that discusses classification of soft ferrite materials used in inductive components for fulfilling the requirements of the electronic industries.
BS EN 61332 also covers the numerical values given are typical values of the parameters of the related materials. Direct translation from the material specification into the core specification is not always easy or possible.
Who is BS EN 61332 - Soft ferrite material classification for?
BS EN 61332 on soft ferrite material is relevant to:
- Ferrite core manufacturers and suppliers
- Transformer and inductor manufacturers
- Telecommunication industry
- Electronics industry
Why should you use BS EN 61332 - Soft ferrite material classification?
Soft ferrite materials impart high electric resistance and thus have outstanding magnetic properties at high frequencies. In this regard, it material classification is beneficial for manufacturers to determine whether the product is fit for purpose.
BS EN 61332 addresses the following issues for ferrite suppliers and users:
- Cross-reference between materials from multiple suppliers
- Assistance to customers in understanding the published technical data in catalogues when comparing multiple suppliers
- Guidance to customers in selecting the most applicable material for each application
- Setting of nomenclature for IEC standards relating to ferrite
- Establishing uniform benchmarks for suppliers for performance in the new development of materials
Compliance with BS EN 61332 can assist you in maintaining uniformity and consistency in the quality and performance of soft ferrite cores material, and making the right selection of soft ferrite materials as per your specific engineering needs.
What’s changed since the last update?
BS EN 60664-3:2017 replaces the second edition published in 2005. This edition includes the following significant technical changes with respect to the previous edition:
- Added "a-wide" rank in subclasses PW3, PW4, and PW5 in Table 3
- Changed "B" of PW3 class from 100 mT to 200 mT; "B × f" and "power loss density" have also been changed
- Changed "B" of PW4 class from 50 mT to 100 mT; "B × f" and "power loss density" have also been changed
