软磁铁氧体磁心IEC标准和国内标准

IEC standards and domestic standards for ferrite cores

铁氧体磁心形状主要有环形、E形、EP形、ETD形、EER形、EC形、EFD形、平面形、罐形、未配对罐形、RM形、PQ形和PM形磁心。介绍了铁氧体磁心的IEC标准和国内标准情况,并对其规格进行了比较。

Ferrite cores include ring cores, E-cores, EP-cores, ETD-cores, EER-cores,EC-cores, EFD-cores, planar cores, P-cores, half pot-cores, RM-cores, PQ-cores and PM-cores. In this paper, IEC and domestic standards for ferrite cores were introduced. On this basis, their dimensions in standards were compared.
