软磁铁氧体材料分类

[中文适用范围]： 本文件规定了满足电子行业要求的电感元件（电感器和变压器）中使用的软铁氧体材料的分类规则。本文件为铁氧体供应商和用户解决了以下问题：来自多个供应商的材料之间的交叉引用；在比较多个供应商时，帮助客户了解目录中公布的技术数据；指导客户为每种应用选择最适用的材料；制定与铁氧体相关的 IEC 标准的术语；为供应商新材料开发绩效建立统一基准。本文件中给出的数值是相关材料的参数（性能）的典型值。从材料规范直接转换为核心规范并不总是容易或不可能的。每一个详细的材料和核心规格都应由用户和制造商达成一致。 [外文原描述]： IEC 61332:2016 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 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 new development of materials. This edition includes the following significant technical changes with respect to the previous edition: a) deleted "c" rank from subclass from Table 3, because of too large power loss density; b) added "a-wide" rank in subclasses PW3, PW4 and PW5 in Table 3; c) changed "B" of PW3 class from 100 mT to 200 mT; "B x f" and "power loss density" have also been changed; d) changed "B" of PW4 class from 50 mT to 100 mT; "B x f" and "power loss density" have also been changed.
