Improving Power-Inductor Performance by Mixing Sub-micro Fe Powder with Amorphous Soft Magnetic Composites

Amorphous soft magnetic powder is one of the most favorable materials for power applications working in the MHz range. In order to induce high permeability, DC bias characteristics, and low core loss in the working frequency range, the core must achieve high packing density. Sub-micro-sized α-Fe pow...
