Abstract
A composition material for use in manufacturing a varistor consists of the following constituents: PA1 a) zinc oxide, PA1 b) ceramic structure influencing additives selected from the group consisting of bismuth oxide, boric acid, chromium oxide, cobalt oxide, manganese oxide and tin oxide, PA1 c) a grain growth influencing additive selected from the group consisting of antimony oxide, silicon dioxide and titanium dioxide, PA1 d) an organic solvent carrier, PA1 e) an organic viscosity influencing additive, and PA1 f) an organic binder. The composition may serve as a ceramic ink for use in the manufacture of multilayer varistors, especially using a screen printing process. A multilayer varistor with pin receiving apertures has a plurality of electrode segments coplanar to each other surrounding the apertures.
