  • Varistor compositions and multilayer varistor
    Patent number: 10233123
    Abstract: A varistor composition free of Sb comprising: (a) ZnO; (b) B—Bi—Zn—Pr glass, or B—Bi—Zn—La glass, or a mixture thereof; (c) a cobalt compound, a chromium compound, a nickel compound, a manganese compound, or mixtures thereof; (d) SnO2; and (e) an aluminum compound, a silver compound, or a mixture thereof. By adjusting the ratio between the components, the varistor composition may be made into a multilayer varistor with inner electrodes having a low concentration of noble metals at a sintering temperature less than 1200° C. The multilayer varistor made from the varistor composition has good maximum surge current, good ESD withstand ability, and low fabrication cost.
