Annotation of standard text IEC 63093-5-ed.2.0 :
IEC 63093-5:2025 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EP-cores made of ferrite, the essential dimensions of coil formers to be used with them 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. It also gives guidelines on allowable limits of surface irregularities applicable to EP-cores. The specifications contained in this document are useful in negotiations between ferrite core suppliers and users about surface irregularities. The general considerations upon which the design of this range of cores is based are as given in Annex A. This edition includes the following significant technical changes with respect to the previous edition: a) revision of Table 2 according to IEC 60205:2016.
