ABSTRACT:
A unitary thick film resistor structure includes a first thick film resistor element formed on one face of a substrate and a second thick film resistor element formed on the opposite face of the substrate. The resistor elements are of complementary, substantially equal and opposite temperature coefficient of resistance characteristics such that when the two elements are connected in parallel to form a unitary structure, the opposite temperature coefficient characteristics provide a stable, mutually compensated low net temperature coefficient of resistance, and exhibiting an immunity to subsequent baking operations incident to the provision of a sintered protective outer coating.
