Ferrite cores. Guidelines on dimensions and the limits of surface irregularities - PQ-cores Ingestion-build-81111 gives recommendations on the design1 Scope This part of IEC 63093 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PQ cores and low profile PQI cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. It also gives guidance on allowable limits of surface irregularities applicable to PQ cores in accordance with the relevant generic
