    Abstract: A metal oxide varistor integrally formed with a heat protection structure that will automatically go to open circuit in conditions of overheating due to sustained over-voltages. The metal oxide varistor integrally formed with a heat protection structure has a body, an insulation bracket, a number of terminals and a fuse. The insulation bracket is deposited on the body and has a number of slots. The fuse connects to the body and one of the terminals. The fuse is mounted one of the slots of the insulation bracket. The fuse reacts to the overheating timely and the melting fuse spreads quickly with the assistance of capillary action evolved by the slots of the insulation bracket to speed up the action to go to open circuit in against damage due to sustained over-voltages.

    Abstract: The manufacturing method for an electroceramic component (1), for example a varistor (1), comprises a laser irradiation of a part (5; 6) of the surface of an electroceramic body (2) before a metallization (3; 4) is applied to the part (5; 6) of the surface. By means of the laser irradiation it is possible to produce a micro-roughness and/or a chemical modification of the surface which permits good adhesion of the metallization, and it is possible to reduce or eliminate areas of unevenness or waviness of that part (5; 6) of the surface of the electroceramic body (2) which is to be metallized. In addition, improved transverse conductivity can be produced, by virtue of which a low contact resistance and a very homogeneous current distribution is achieved, in particular near to the metallization (3; 4). In addition it is possible to remove residues which originate in particular from a sinter support or from the application of a passivation layer. After the laser irradiation, the electroceramic body advantageously has a border (9) which adjoins the part (5; 6) of the surface and which is not laser-irradiated. The laser beam can advantageously be pulsed and focused.

    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 invention is a MOV based surge arrester that uses MOVs manufactured from a recently patented process. These new technology MOVs are significantly more uniform in their composition, resulting in more uniform performance. Each MOV is packaged by placing it between a pair of contact plates, preferably manufactured from aluminum. This packaging significantly increases the surface area between the contact plates and the MOVs. Wiring is minimized. Also, the use of the metal plates increases the ability of a surge suppresser to remove the heat generated in severe over-voltage situations. The preferred embodiment teaches conductor wires soldered to a disk in a grid pattern. The grid pattern provides a low empedance connection and prevents failure of the MOV at a lower than expected voltage. Grid patterns can include spiral, serpentine S, and square patterns.
