Patent ID: 7042328

Claim:
A high power resistor comprising: a resistance element having first and second opposite ends and opposite edges extending between the first and second opposite ends; first and second leads comprised of a material different from the material of the resistance element, the first and second leads being operatively attached to the first and second opposite ends of the resistance element; a heat sink comprised of dielectric material and being a good heat conductor; a heat conducting adhesive between the resistance element and the heat sink and adhering the resistance element to the heat sink for conducting heat from the resistance element to the heat sink, the adhesive having properties of maintaining the structural integrity and adhesive capabilities of the adhesive in the temperature range of −65 degrees Centigrade to +275 degrees Centigrade; a pre-molded body having a first and second edges extending between the first and second opposite ends of the resistance element retentively engaging the resistance element and including at least two ridges extending along the opposite edges of the resistance element; the heat conducting adhesive and the heat sink being positioned between the opposite edges of the pre-molded body; a molding compound molded at a separate time from the pre-molded body to create a molded body surrounding the resistance element, the pre-molded body, and the adhesive, and partially surrounding the heat sink.
