标准范围

IEC 63093-4:20 19规定了对于优选范围的由铁氧体制成的RM磁芯和薄型RM磁芯的机械互换性至关重要的尺寸，以及它们的端子引脚在2.54 mm印刷布线网格上相对于磁芯基本轮廓的位置。它还根据相关通用规范给出了适用于RM型芯的表面不规则性允许限值的指导。本文件核心尺寸的选择基于包括工业标准尺寸的理念，无论是通过纳入国家标准还是通过在工业中广泛使用。本文件是铁氧体磁芯制造商和客户之间关于表面不规则性的谈判中有用的规范。本第一版取消并取代IEC 62317第一版-2005年发布的4和2015年发布的IEC 60424-2第二版。本版构成技术修订版。本版本包括以下与IEC 62317-4:20 05和IEC 60424-2:20 15相关的重大技术变更:a)IEC 63093-4整合了IEC 62317-4:20 05和IEC 60424-2:20 15的内容；b)IEC 60424-2:20 15表2已作为表C.1纳入附录C。

IEC 63093-4:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of RM-cores and low-profile RM-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. It also gives guidance on allowable limits of surface irregularities applicable to RM-cores in accordance with the relevant generic specification.
The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry.
This document is a specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities.
This first edition cancels and replaces the first edition of IEC 62317-4 published in 2005 and the second edition of IEC 60424-2 published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC 62317-4:2005 and IEC 60424-2:2015:
a) IEC 63093-4 integrates the contents of IEC 62317-4:2005 and IEC 60424-2:2015;
b) IEC 60424-2:2015, Table 2, has been included in Annex C as Table C.1.
