EN IEC 63093-5:2018

IEC63093-5:2018(E) 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 2,50mm 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 manufacturers and users about surface irregularities. The general considerations upon which the design of this range of cores is based are as given in AnnexA.This edition includes the following significant technical changes with respect to IEC62317-­5:2015:a.addition of the limits of surface irregularities.
