Abstract
A resistor device comprises a first film of resistive material deposited on a dielectric substrate and having two terminal portions for connection to an electrical circuit, and a second film of resistive material deposited on the substrate in thermally-conductive contact with the first film and electrically isolated therefrom. The material of one of the films has a relatively high temperature coefficient of resistance, so that the resistance of that film can be utilized as an indication of the temperature of the other film.
