95 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.

Explanation of Part Numbers: Digits 1 & 2 = product class and 3 & 4 = material grade.
AL value is measured at 1 kHz, B < 10 gauss.
A low loss MnZn ferrite material for power applications up to 200 kHz with low temperature variation. New type of 95 material is a low loss power material which features less power loss variation over temperature (25-100°C) at moderate flux densities for operation below 200 kHz.
Available in 95 material:
