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.
