Patent ID: 6892443

Claim:
A method of manufacturing a 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 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 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 selected to contribute to a cumulative effect of reduction of resistance change due to power; and cementing a second 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 to a second surface of the substrate opposite the first surface, the first and second resistive foils patterned to have approximately equal resistance value.
