1 Scope
This part of IEC 62317 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 general considerations upon which the design of this range of cores is based are
as given in Annex A.
