标准摘要
[中文适用范围]： IEC 63093-5:2025 RLV 包含官方的 IEC 国际标准及其红线版本。红线版本仅提供英文版，可帮助用户快速、轻松地比较官方 IEC 标准与其前一版之间的所有变更。IEC 63093-5:2025 规定了对于由铁氧体制成的优选 EP-磁芯系列在机械互换性方面具有重要意义的尺寸、与之配套使用的线圈骨架的基本尺寸，以及其终端引脚在 2.5 mm 印刷电路网格上相对于磁芯基线轮廓的位置，以及在相关计算中应使用的有效参数值。该标准还提供了适用于 EP-磁芯的表面不规则允许限度的指南。本文件中的规范有助于铁氧体磁芯供应商与用户之间就表面不规则问题进行协商。该系列磁芯的设计依据在附录 A 中给出。与前一版相比，本版包含了以下重大技术变更：a) 根据 IEC 60205:2016 修订表 2。 [外文原描述]： IEC 63093-5:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 63093-5:2025 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 suppliers 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 the previous edition: a) revision of Table 2 according to IEC 60205:2016.
