PQ Cores (6698404121)Part Number: 6698404121
98 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 ALvalue.
Weight indicated is per pair or set.
