DANSK DSF/PREN IEC 63093-10 PDF

This part of IEC 63093 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PM-cores made of magnetic oxides, the main dimensions for coil formers to be used with these cores and the locations of their pins on a modular printed wiring grid in relation to the base outlines of cores. It also specifies the effective parameter values to be used in calculations and gives guidelines on allowable limits of surface irregularities applicable to the PM-cores. The use of derived standards which give a more detailed specification of component parts whilst still permitting compliance with this standard is discussed in Annex A.
