IS 9652 : 1980 Dimensions for Magnetic Oxide Cores and Associated Coil Formers for Use in Power Supplies (Ec-cores)

UDC 621.318.13.042.1 : 006.78 : 621.311                      LTD13

Reaffirmed 2020

1 Scope

1.1 This standard specifies the physical and magnetic dimensions of EC-Cores made of magnetic oxides for use in high flux density applications and covers preferred dimensions of these cores together with their tolerances as far as these are of importance for mechanical and electrical interchangeability.

Note - This high flux density application specifically covers cores designed for use in power transformers, for example, for switched mode power supplies operating typically at 25 kHz switching frequency.
