Реферат: CYLINDRICAL VARISTOR AND METHOD OF MAKING THE SAME Abstract of the Disclosure A varistor has a cylindrical core made of a sintered varistor material which includes a longitudinal opening between the core ends. A pair of terminating layers are applied to the core, each adhering to one of the ends of the core and being in electrical contact with a lead wire inserted into the longtidinal opening. An electrode film is applied to the outer longitudinal surface of the core with each end in communication with one of the terminating layers. The electrode film is divided between the terminating layers into a pair of electrode portions by a gap which is dimensioned to predetermine the electrical properties of the varistor. The preferred method of manu-facture involves forming a sintered, cylindrical core of varistor material with a longitudinal opening; applying a terminating layer to each end of the core; applying an electrode film to the core surface with each end of the core in contact with one of the terminating layers; dividing the film into a pair of electrode portions by forming a gap between the ends of the film; and inserting a lead wire into each end of the core opening in contact with one of the terminating layers.
