Abstract
A voltage-dependent resistor comprising a sintered body comprising ZnO as a major part and additives wherein at least 10 weight percent of the ZnO is composed of ZnO grains having a grain size in the range from 100 to 500 microns; and method of making the same wherein the starting mixture comprises ZnO grains having a grain size in the range from 20 to 200 microns. This voltage-dependent resistor has both a low C-value and a high surge energy withstanding capability. It also has a low leakage current at a high temperature due to the addition of an antimony component as a spinel type polycrystalline Zn.sub.7/3 Sb.sub.2/3 O.sub.4.
