ABSTRACT:
A voltage-dependent nonlinear resistor containing ZnO as a main component and six auxiliary components, i.e., (1) a rare earth element; (2) Co; (3) at least one of Mg and Ca; (4) at least one of K, Rb and Cs, (5) as well as Cr; and (6) B which may be combined with at least one of Al, Ga and In. Alternatively, the auxiliary components may be (1) a rare earth element; (2) Co; (3) at least one of K, Rb and Cs; (4) Cr; (5) B; and (6) at least one of Al, Ga and In. The voltage-dependent nonlinear resistor of the present invention has high resistance to both long and short wave-tail surge currents and has an extended service life without sacrificing good nonlinearity.
