Foreword

This document conforms to GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting is scheduled.

This document adopts IEC 63299:2022 "Classification of metal magnetic powder cores".

The following minimal editorial changes have been made to this document.

--To align with existing standards, the standard name has been changed to "Classification of Metallic Magnetic Powder Core Materials".

Please note that some content in this document may involve patents. The issuing organization of this document assumes no responsibility for identifying patents.

This document was proposed by the Ministry of Industry and Information Technology of the People's Republic of China.

This document is under the jurisdiction of the National Technical Committee on Standardization of Magnetic Components and Ferrite Materials (SAC/TC 89).

1 Scope

This document specifies the classification of metal magnetic powder core materials (hereinafter referred to as "magnetic powder core materials") used in inductive components that meet the requirements of the electronics industry.

rule.

This document provides the following guidance for suppliers and users of metal magnetic powder core materials.

--Comparison of magnetic powder core materials from multiple suppliers;

--When comparing multiple suppliers, assist users in understanding the technical data published in each product catalog;

--Guide users to select the most suitable magnetic powder core material for each application;

--To establish a unified benchmark for the performance of new magnetic powder core materials developed by suppliers.

The values given in this document are typical values for the relevant material parameters. Directly converting material technical parameters to core technical parameters is not...

It's always easy; some things are even impossible.

The detailed specifications for each material and core will be agreed upon by the user and the supplier.
