IEC 63093的本部分规定了对铁氧体制成的ETD磁芯优选范围的机械互换性具有重要意义的尺寸，以及与之配套使用的线圈成型机的基本尺寸，以及在涉及它们的计算中使用的有效参数值。它还提供了适用于ETD型芯的表面不规则性允许极限的指南。 本文件中包含的规范对于铁氧体磁芯制造商和用户就表面不规则性进行谈判非常有用。 附录A中讨论了衍生标准的使用，这些衍生标准给出了更详细的零部件规范，同时仍允许遵守本文件。交叉引用:IEC 60205IEC 60401-1EN 60424-1EN 60401-1IEC 60424-1EN 60205EN 60424-3:2016IEC 62317- 6:2015IEC 60424-3:2015EN 62317-6:2016购买本文件时提供的所有现行修订版均包含在购买本文件中。

This part of IEC 63093 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ETD-cores made of ferrite and the essential dimensions of coil formers to be used with them, as well the effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to ETD-cores. The specifications contained in this document are useful in negotiations between ferrite core manufacturers and users about surface irregularities. The use of derived standards which give more detailed specifications of component parts while still permitting compliance with this document is discussed in Annex A.Cross References:IEC 60205IEC 60401-1EN 60424-1EN 60401-1IEC 60424-1EN 60205EN 60424-3:2016IEC 62317-6:2015IEC 60424-3:2015EN 62317-6:2016All current amendments available at time of purchase are included with the purchase of this document.
