铁氧体磁芯 - 尺寸 - 第13部分:用于电源应用的Pq磁芯

[中文适用范围]： 本部分IEC 62317规定了对于由铁氧体制成的优选范围的PQ磁芯和低轮廓PQI磁芯的机械互换性至关重要的尺寸，以及其端子引脚在2.54毫米印刷布线网格上相对于磁芯底面轮廓的位置。本标准磁芯尺寸的选择基于包括工业标准的哲学思想，无论是通过纳入国家标准的范围，还是通过工业中的广泛使用。见IEC 62317-1以获取更多关于选择包含的磁芯尺寸的哲学的细节。设计该系列磁芯的一般考虑见附录A。 [外文原描述]： IEC 62317-13:2015 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. The selection of core sizes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. This edition includes the following significant technical changes with respect to the previous edition: a) addition of three core sizes (PQ 65/54, PQ 78/39 and PQ 107/87) in Table 1; b) addition of effective parameter and Amin values, of main dimensions of coil formers and of gauge dimensions for PQ-cores for PQ 65/54, PQ 78/39 and PQ 107/87.
