Specifies the physical and magnetic dimensions of EC-cores made of magnetic oxides for use in high flux density applications. Specifically covers cores designed for use in power transformers, for example for switched mode power supplies operating typically at 25 kHz switching frequency. Lists preferred dimensions of cores together with their tolerances as far as these are of importance for mechanical and electrical interchangeability.
