ABSTRACT:
A voltage-dependent resistor comprising a sintered body comprising ZnO as a major part and Bi.sub.2 O.sub.3 and GeO.sub.2 as additives with electrodes applied to the opposite surfaces of the sintered body. This voltage-dependent resistor has a low C-value and a high n-value in I=(V/C).sup.n along with high power dissipation for surge energy and high stability to a high D.C. load. Further, other additives such as NiO, Co.sub.2 O.sub.3, MnO, TiO.sub.2 and Cr.sub.2 O.sub.3 can advantageously be added to the sintered body.
