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 PCB layout.

The new EQ geometries are available in Sendust (MS), FluxSan™ (FS) and Hi-Flux™ (HF) and materials with 26, 40 and 60 permeability. This new part series have been incorporated into the Micrometals Online Inductor Design Tool, for facilitating design optimization and material selection:

EQ magnetic cores are also well suited for design of high performance switch-mode power converters and offer the following advantages: 

•Low Profile – low total height.

•Good geometry for low flux leakage.

•Excellent shape for high current applications.

•Large core surface to contact heat sink
