Patent ID: 7278201

Claim:
A method of manufacturing a resistor with suitable properties for use as a high precision power resistor comprising: providing a substrate having a modulus of elasticity of about 10×10 6 psi to about 100×10 6 psi and a thickness of about 0.5 mils to about 200 mils, the substrate shape and substrate type selected to contribute to a cumulative effect of reduction of resistance change due to power; providing a first resistive foil having a low TCR of about 0.1 to about 1 ppm/° C. and a thickness of about 0.03 mils to about 0.7 mils, the first resistive foil having a foil type, a pattern, and an inherent temperature coefficient of resistance selected to contribute to a cumulative effect of reduction of resistance change due to power; cementing the first resistive foil to a first surface of the substrate with a cement having a cement type and a cement thickness selected to contribute to a cumulative effect of reduction of resistance change due to power by controlling effects of a temperature differential across the thickness of the substrate created by applying power to the first resistive foil.
