POT CORES

As pot cores are one of the oldest core designs, they are available in a wide range of worldwide standardized sizes – according to IEC 62317-2. Originally produced for filter inductors, pot cores are becoming increasingly popular in power applications. With the introduction of 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.
