1 Scope

This part of GB/T 36103 specifies the important dimensions related to the mechanical interchangeability of the preferred series of EFD magnetic cores and the magnetic core. The basic dimensions of the coil bobbin used and the values of the effective parameters used for calculating such cores. This section is based on the principle of selecting the core size. national standards and core sizes widely used and shaped in the industry. Relevant election See IEC 62317-1 for more details on core selection. Appendix A gives the general principles for designing such cores.
