DIN EN 62317-5:2016-07

EP cores are mainly used in filters and small transformers. With appropriate ferrite materials, they can be used up to a frequency range of 500 kHz. This standard specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EP-cores, the essential dimensions of coil formers to be used with these cores and the locations of their terminal pins on a 2,50 mm printed wiring grid in relation to the base outlines of the cores, and the effective parameter values to be used in calculations involving them. The main change with respect to the previous edition concerns the inclusion of the EP5 core size. The responsible committee is DKE/K 625 "Magnetische Bauelemente und deren Komponenten" ("Magnetic devices and their components") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
