  • Patent number: 7921546
    Abstract: A method for making a high current low profile inductor includes forming an inductor element comprising a coil having an open center and an outside surface, the coil also having first and second coil ends, making a dry mixture comprising a dry resin and an insulated dry powdered magnetic powder, and compressing the dry mixture around the outside surface of the coil and within the open center of the coil to create an inductor body without liquefying the dry mixture, whereby the inductor body engages the coil both within the coil open center and also the coil outside surface.

  • Patent number: 6946944
    Abstract: A high current, low profile inductor (IHLP) includes a conductive coil molded within an inductor body substantially free from ferrite materials and comprising powdered iron materials. The method comprises pressure molding the inductor body substantially free from ferrite materials and comprising a powdered magnetic material within the hollow core of the coil and completely around the coil so that the magnetic material is substantially free from voids therein without shorting out the coil.

  • Patent number: 6460244
    Abstract: A method for making a high current, low profile inductor includes a wire coil having an inter coil end and an outer coil end. A magnetic material completely surrounds the wire coil to form an inductor body. First and second leads connected to the inner coil end and the outer coil end respectively extend through the magnetic material to the exterior of the inductor body. The method of operation involves pressure molding the magnetic material around the wire coil.
