PURPOSE:To provide the title voltage non-linear resistor with the lower varistor voltage, the smaller limited voltage and the enhanced high temperature loaded life characteristics by a method wherein said resistor contains zinc oxide as the main constituent with specific mole % of subconstituents as well as specific wt.% of borosilicate lead glass existing in the particle field. CONSTITUTION:The title resistor contains zinc oxide as the main constituent as well 0.1-2.0 mole % of bismuth expressed in terms of Bi2O2, 0.05-3 mole % of cobalt expressed in terms of CoO, 0.05-3.0 mole % of manganese expressed in terms of MnO2, 0.001-0.20 mole % of antimony expressed in terms of Sb2O2 and 0.10-2.0 mole % of titanium expressed in terms of TiO2 as the subconstituents. Besides, 0.01-1.0wt.% of borosilicate lead glass is added to the mixed material of the main and subconstituents. Through these procedures, the title resistor can be provided with a lower varistor voltage, a smaller limited voltage ratio, an excellent surge resistance and high temperature load characteristics. |
