标准摘要
[中文适用范围]： IEC 63093 的这一部分规定了对于由铁氧体制成的优选范围的 EP 磁芯的机械互换性非常重要的尺寸、与其一起使用的线圈架的基本尺寸以及它们在 2,50 上的端子引脚的位置。毫米印刷布线网格与磁芯基本轮廓的关系以及涉及它们的计算中使用的有效参数值。它还给出了适用于 EP 磁芯的表面不规则性允许极限的指南。本文件中包含的规格对于铁氧体磁芯制造商和用户之间关于表面不规则性的谈判很有用。该系列内核设计所依据的一般考虑因素如附录 A 所示。 [外文原描述]： IEC 63093-5:2018 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EP-cores made of ferrite, the essential dimensions of coil formers to be used with them and the locations of their terminal pins on a 2,50 mm printed wiring grid in relation to the base outlines of the cores and the effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to EP-cores. The specifications contained in this document are useful in negotiations between ferrite core manufacturers and users about surface irregularities. The general considerations upon which the design of this range of cores is based are as given in Annex A. This edition includes the following significant technical changes with respect to IEC 62317-5:2015: a. addition of the limits of surface irregularities.
