标准摘要
[中文适用范围]： IEC 62317 的这一部分规定了对于优选范围的 RM 磁芯和由铁氧体制成的薄型 RM 磁芯的机械互换性非常重要的尺寸，以及它们在 2.54 mm 印刷布线网格上的端子引脚位置与核心的基础轮廓相关。它还指定了用于电感测量的测试条件和夹紧力。附录 A 中给出了该系列内核设计所依据的一般考虑因素。 [外文原描述]： IEC 62317-4:2005 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 specifies the test conditions and clamping forces to be used for inductance measurement. This international standard cancels and replaces the second edition of IEC 60431 published in 1983, its amendment 1 (1995), and its amendment 2 (1996). This international standard constitutes a technical revision of IEC 60431. The contents of the corrigendum of July 2016 have been included in this copy.
