Abstract
A metal strip resistor is provided with a resistive element disposed between a first termination and a second termination. The resistive element, first termination, and second termination form a substantially flat plate. A thermally conductive and electrically non-conductive thermal interface material such as a thermally conductive adhesive is disposed between the resistive element and first and second heat pads that are placed on top of the resistive element and adjacent to the first and second terminations, respectively.
Claims5
A method for making a metal strip resistor, the method comprising:
- providing a resistive element disposed between a first termination and a second termination, wherein the resistive element, first termination, and second termination form a substantially flat plate;
- providing a heat pad carrier containing at least two heat pads;
- dispensing an adhesive onto at least one of the resistive element or the at least two heat pads, wherein the adhesive is thermally conductive and electrically non-conductive;
- mating the resistive element and first and second terminations to the heat pad carrier such that one of the at least two heat pads is adjacent to the first termination and the other one of the at least two heat pads is adjacent to the second termination;
- and
- separating the at least two heat pads from the heat pad carrier.
