标准摘要
[中文适用范围]： 本文档规定了铁氧体PQ磁芯和低轮廓PQI磁芯机械互换性所必需的尺寸，以及这些磁芯的端子引脚在2.54毫米印制电路网格上相对于磁芯基面轮廓的位置。它还提供了关于适用于PQ磁芯的表面不规则性允许极限的指导，符合相关通用规范。本文档中磁芯尺寸的选择基于纳入行业标准的原则，无论是通过纳入国家标准还是通过在工业中的广泛使用。本文档是铁氧体磁芯制造商与客户就表面不规则性进行谈判时使用的规范。有关该系列磁芯设计的一般考虑因素见附录A。 [外文原描述]： IEC 63093-13:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PQ-cores and low-profile PQI-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 PQ-cores in accordance with the relevant generic specification. This first edition cancels and replaces the second edition of IEC 62317-13 published in 2015 and the first edition of IEC 60424-8 published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions of IEC 62317-13 and IEC 60424-8: a) IEC 63093-13 integrates IEC 62317-13 and IEC 60424-8; b) IEC 60424-8:2015, Table 1, has been included in Annex B as Table B.1. The contents of the corrigendum of May 2024 have been included in this copy.
