- 适用范围
- This part of IEC 62317 specifies the dimensions that are of importance for mechanical interchangeability for E-cores with rectangular cross-section made of ferrite, the dimensions of coil formers to be used with them, and the effective parameter values to be used in calculations involving them. The selecting core sizes to this standard is based on the philosophy of including those sizes, which are industrial standards, either by inclusion in national standards, or by broad-based use in industry. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. NOTE Cores covered by this standard are intended for general applications at both low and high flux densities, but they also find uses in special applications such as pulse transformers. They are generally used in pairs. Whilst the main application of this standard is expected to be for ferrite cores, its validity for iron powder cores should not be overlooked. Coil formers are not specified for E-cores smaller than E 8/2, which are also used in SMD assemblies. The use of “derived” standards, which give a more detailed specification of component parts whilst still permitting compliance with this standard, is discussed in Annex A.

电感简介及电感失效分析（一）
空心电感器不用磁心、骨架和屏蔽罩等，而是先在模具上绕好后再 脱去模具，并将线圈各圈之间拉开一定距离。 2）绕组：指具有规定功能的一组线圈，有单层和多层之分。单层有密绕和间绕两种形式；多层有分层平绕、乱绕、蜂 房式绕法等多种。 3）磁心：一般采用镍锌铁氧体或锰锌铁氧体等材料，它有“工”字形、柱形、帽形、“E”形、罐形等多种形状。 铁心：主要有硅钢片、坡莫合金等，其外形多为“E”型。 ...
