High DC Bias Magnetic Core

High DC Bias Magnetic Core

Sendust Core is made from 6%Al,9%Si and 85%Fe. It is mainly used to replace iron powder core as its core loss is 80% less than the powdered iron, so it can be applied with the frequency above 8kHz.

High Flux core:

High Flux cores has a higher energy storage capability and more effective permeability when compared to the performance of gapped ferrite ore powdered iron cores of a similar size. Excellent DC-Bias characteristics, low core losses.  High Flux core are an excellent choice for applications such as PFC reactors, switching regulator inductors, in-inline noise filters. pulse transformers.
