ABSTRACT:
A "varistor" or voltage-dependent nonlinear resistor employs a ceramic base body having a voltage-dependent nonlinearity. First and second lead-out electrode layers are formed on first and second external surfaces, respectively, of the ceramic base body. Within and enclosed by the ceramic base body, a plurality of internal electrodes extend in parallel with each other and connect to the external lead-out electrodes. Also, the invention provides a method of manufacturing the voltage-dependent nonlinear resistor comprising the steps of forming a plurality of raw sheets of material, each having the desired voltage-dependent nonlinearity characteristics, after sintering. Internal electrodes of conducting material are printed on each of these sheets. The sheets are then laminated, cut and formed with external electrodes connecting the internal electrode to each other.
