Abstract: A method is disclosed for producing a non-linear powder having microvaristor particles which have a non-linear current-voltage characteristic. The production steps includes mixing non-metallic particles with the microvaristor particles, thermally treating the non-metallic particles for decomposing them into electrically conductive particles and fusing the electrically conductive particles onto the microvaristor particles. Embodiments, among other things, relate to: breaking up agglomerates of the non-metallic particles during mixing; keeping the decomposition temperature below a sintering or calcination temperature of the microvaristor particles; and choosing micron-sized or nano-sized non-conductive particles for microvaristor decoration. The production method produces varistor powder with improved reproducibility of the non-linear electric current-voltage characterstic and with reduced switching fields (Es).

Abstract: Metal oxide varistors (MOVs) are employed in surge protection devices, such as overvoltage protection devices, between a pair of signal lines and ground to reduce the capacitive imbalance introduced by the overvoltage protector, thereby improving higher frequency transmissions over twisted-pair telephone lines. The MOVs are sorted into subgroups having a capacitive tolerance of no more than about 1.0 picofarad. MOVs with asymmetrical electrodes can also be sorted to reduce both the capacitance and the capacitive tolerance of the MOVs. The sorted MOVs can then be electrically connected in parallel with a gas discharge tube on each signal line to produce an overvoltage protection device, for example a station protector for use at a customer premises, having a capacitive imbalance that does not exceed about 1.3 picofarads. The use of asymmetrical electrodes reduces the capacitance of the sorted MOVs to less than about 30 picofarads.

Abstract: The method is used to produce a varistor which has a cylindrical resistance body (1) made from a material based on metal oxide, and two electrodes (2, 3) which are each arranged on one of two mutually parallel end faces of the cylindrical resistance body (1). In a first method step, a layer of electrode material is applied to both end faces, as far as their outer boundary (9), which is designed as a sharp edge. In a second method step, a circular ring (4), which is delimited by the outer boundary (9), runs to as far as the end face of the resistance body (1) and has a width of from approx. 10 to 500 &mgr;m, is removed from the electrode, or the resistance body (1) and electrode are beveled (5′) at the outer boundary. The method allows simple and economic manufacture of a varistor.

Abstract: A metal oxide varistor comprises a hollow ceramic body having an opening, a first electrode within the body and having a portion extending through the opening, and a second electrode disposed on the exterior surface of the body. Voltage applied to the electrodes above the device clamping voltage causes the ceramic body to conduct. The geometry of the body, which is optimally a sphere, greatly increases surface area between the electrodes and the ceramic body, and consequently increases the device's current carrying capacity.
