ABSTRACT:
Non-linear voltage-dependent resistor having a ceramic sintered body based on zinc oxide as a resistance material which is doped with at least one alkaline earth metal, rare earth metal and metal of the iron group present as an oxide and is doped with at least one of the metals from the group aluminum, gallium and/or indium and having electrodes provided on oppositely located major surfaces of the sintered body, in which the sintered body is constructed from several layers having at least a layer structure of one layer of resistance material on a carrier layer based on zinc oxide which has a higher electric conductivity as compared with the resistance material, as well as a method of manufacturing same.
