ABSTRACT:
A magnetic powder composition suitable for manufacturing a powder core used in a reactor or transformer connected to a semiconductor switching element, essentially consists of a powder of a soft magnetic metal or alloy or a mixture of these, an electrically insulating binder polymer for binding the powder, and a coupling agent of an organic metallic compound for coupling the powder and the binder polymer. The obtained powder core has excellent frequency characteristics of magnetic permeability, a high magnetic flux density, and a small iron loss at high frequencies.
