  • Thin-film resistor and resistance material for a thin-film resistor
    Patent number: 5994996
    Abstract: A metal alloy having an intrinsically low TCR, and which preferably comprises a metal oxide and forms part of the resistance material in a quantity of 15-60 vol. %. The best results are achieved with a resistance material which comprises an alloy of CuNi as the metal alloy and SiO.sub.2 as the high-ohmic component. The resistors exhibit a relatively high resistance value as well as a relatively low TCR value.
