Abstract
An electrically resistive film of the type used for forming thick film resistors is formed predominantly of palladium and includes an addition of boron nitride to increase resistance, preferably in combination with tantalum oxide. A paste of palladium powder and boron nitride powder dispersed in a vaporizable vehicle is applied to a substrate and sintered to form the film. In a preferred embodiment, the substrate is a ceramic powder compact that is concurrently sintered in a co-firing process.
