Pot cores are on of the oldest core designs, they are
available in a wide range of worldwide standardised sizes -according to IEC 133.
Originally produced for filter inductors, pot cores are
becoming increasingly in power applications. With the
introduction of new EMC legislation, electromagnetic
screening has become a prime concern in core selection. The pot core's shape almost
completely encloses the windings and whilst this can be a
hindrance for access purposes, it provides excellent
screening.
