PQ Cores (6678211621)

Part Number: 6678211621

78 PQ CORE SET

PQ cores were developed for use in power applications. The large surface area to volume of the core aids in heat dissipation. PQ

cores are employed both in filter and transformer designs for switch mode power supplies.

PQ cores can be supplied with the centerpost gapped to a mechanical dimension or an A_Lvalue.
