Abstract:
A high current, low profile inductor (IHLP) comprising:a conductive coil having an inner coil end, an outer coil end, a plurality of coil turns, and a hollow core;a first conductive lead connected to said inner coil end;a second conductive lead connected to said outer coil end;an inductor body substantially free from ferrite materials and comprising a uniform mixture of first and second powdered iron particles, said first powdered iron particles and said second powdered iron particles having electrical characteristics different from one another;said uniform mixture of said first and second iron particles completely surrounding and contacting all of said conductive coil and portions of said first and second conductive leads, and also completely filling said hollow core;said first and second iron particles being pressure molded within said hollow core and around said conductive coil and said portions of said first and second leads so that said first and second powdered iron particles of said inductor body are substantially free from voids therein and are compressed tightly completely around and in contact with all portions of said conductive coil and said portions of said first and second leads without shorting out said coil or said leads.
