IEC？63093-13:20 19规定了对于由铁氧体制成的优选范围的PQ磁芯和薄型PQI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的基本轮廓的位置。它还根据相关通用规范给出了适用于PQ型芯的表面不规则性允许限值的指导。 这个第一版取消并取代了IEC的第二版？2015年出版的62317-13和IEC第一版？60424-8发表于2015年。本版构成技术修订版。 与以前的IEC版本相比，该版本包括以下重大技术变化？62317-13？IEC呢？60424-8: a）IEC？63093-13整合IEC？62317-13和IEC？60424-8; b）？IEC？60424-8:20 15，表1，已作为表B.1纳入附录B。

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.
