19、1 Scope 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 th
20、em. 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 inc
21、luded. 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 ferri
22、te 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
23、with this standard, is discussed in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any am
24、endments) applies. IEC 60205:2006, Calculation of the effective parameters of magnetic piece parts 3 Primary standards Compliance with the following requirements ensures mechanical interchangeability of complete assemblies and coil formers. 3.1 Dimensions of E-cores with rectangular cross-section 3.
25、1.1 Main dimensions The main dimensions of E-cores with rectangular cross-section shall be as given in Table 1. NOTE The dimensions of the cores may be checked by means of gauges, an example of which is given in Annex B. In order to facilitate production it may be necessary to use gauges having dime
26、nsions differing from those given in Annex B, although no relaxation of the requirements for the dimensions of the cores given in Table 1 is thereby permitted. 3.1.2 Effective parameter and Aminvalues The effective parameter and Aminvalues of a pair of cores whose dimensions comply with 3.1.1 shall
27、be as given in Table 2 (see IEC 60205, for the definitions of these parameters and their calculation; and 2.2 of IEC 60205, for the definition of Amin). 4 EN 62317-8:2006Licensed Copy: Wang Bin, na, Tue Mar 27 03:22:58 GMT+00:00 2007, Uncontrolled Copy, (c) BSIF E A DBCIEC1608/06Figure 1 Dimensionso
