ABSTRACT:
A paste composed of Li.sub.2 CO.sub.3, SiO.sub.2, Sb.sub.2 O.sub.3 and Bi.sub.2 O.sub.3 is coated and baked on a side surface of a sintered ZnO based nonlinear voltage dependent resistor body to form a high resistance side surface for improving a impulse current withstand of the resistor.
The amount of the paste constituent is 1.about.2.5 mol % for Li.sub.2 CO.sub.3, 72.+-.5 mol % for SiO.sub.2, 20.+-.3 mol % for Sb.sub.2 O.sub.3 and 8.+-.2 mol % for Bi.sub.2 O.sub.3.
