Abstract
This invention relates to resistor compositions comprising, in % by weight, about 5-24% RuO.sub.2, about 10-20% Ag, about 3-8% Sb.sub.2 O.sub.3, about 8-12% CdO, about 35 to 70% lead-borosilicate glass, up to about 4% Ta.sub.2 O.sub.5 and up to about 2% thermistor powder such as at least one of the transition metals Mn.sub.2 O.sub.3, NiO, CuO, Cr.sub.2 O.sub.3 and ZnO. These resistor compositions are adapted to be dispersed in a liquid vehicle to form a resistor ink or paste that can be applied to a surface of a ceramic substrate and fired to form a resistor having stable electrical and mechanical properties.
