ABSTRACT:
A voltage-dependent resistor having a low operational field strength with a ceramic sintered body on the basis of a polycrystalline alkaline earth metal titanate doped with a small quantity of a metal oxide so as to produce an N-type conductivity, in which the sintered body comprises at its grain boundaries insulating layers formed by in-diffusion of at least a metal oxide or at least a metal oxide compound and comprises of an alkaline earth metal titanate having Perowskite structure of the general formula:
