Abstract
A voltage-dependent resistor comprising a sintered body consisting essentially of ZnO, as a main constituent, and, as additives, bismuth oxide (Bi.sub.2 O.sub.3), cobalt oxide (CoO) and/or manganese oxide (MnO) and/or aluminum oxide (Al.sub.2 O.sub.3) and gallium oxide (Ga.sub.2 O.sub.3) and/or indium oxide (In.sub.2 O.sub.3) with electrodes applied to the opposite surfaces of the sintered body. This voltage-dependent resistor has a low C-value, a high n-value, high power dissipation for surge energy and a high stability to a high D.C. load. Other additives such as titanium oxide (TiO.sub.2), chromium oxide (Cr.sub.2 O.sub.3) and nickel oxide (NiO) improve the voltage dependent property of the sintered body.
