New PQ Geometry Series

Introducing new PQ distributed gap cores for high frequency switch-mode power applications.

Micrometals is proud to introduce a new series of PQ distributed gap cores.  The rectangular geometry of the PQ body is ideal for surface mount applications while the round center post readily accepts helical flat wire coils, or bobbins with round wire.  The cores are offered in six industry standard geometries from 21mm to 51mm, three exclusive material formulations, and three reference permeability values.

The new PQ geometries are available in Micrometals exclusive material formulations of Sendust (MS), Hi-Flux™ (HF) and FluxSan™ (FS - Iron Silicon) with 26, 40 or 60 permeability values.&nbs...

New EQ Geometries

New EQ Geometries

Micrometals APC is proud to introduce a new EQ shape series. The EQ geometry is  similar to low profile E-core but with a round center-post and rounded outside legs.  The round center  post is convenient for heavy gauge wire such as helically wound flat wire coils or bobbins with round wire. The round post minimizes the conductor length per turn which keeps winding resistance low and allows for high density designs.

The initial core series is offered with industry standard sizes from 20mm to 50mm, however, custom sizes are welcome. The EQ shape is an excellent choice for surface mount inductors and rectangular outer dimensions allow to optimization...
