Abstract
The invention discloses a self-limiting ceramic capacitor characterized by high capacitance and transient voltage protective properties comprising a plurality of thin layers of a zinc oxide-based ceramic material having non-linear resistance characteristics with each layer having a conductive coating on at least one surface thereof and the coated ceramic layers sintered together to form a laminated stack. A conductive coating comprising a first electrode of the capacitor is formed on a first edge of the laminated stack of layers and is in electrical communication with a portion of the conductive coating on some of the layers extending to that edge of the layer. Conductive material comprising a second electrode of the capacitor is formed on a second and opposite edge of the laminated stack of layers in electrical communication with a portion of the conductive coating on at least some of the other layers in the plurality of layers having a portion of the conductive coating thereon extending to the second and opposite edge of the layers.
