THE FABRICATION METHEOD OF LOW VOLTAGE BULK TYPE VARISTOR BY CONTROLING THE BOUNDARY NUMBER BETWEEN ELECTRODES

摘要

The varistor, which protects the elements of the circuit from surge voltages in electronic products is published.; Between the varistor element of the present invention stacked chip varistor element and unlike bulk type varistor to the use of grain boundaries existing on the surface of the device by using a device such as a screen printer to the varistor surface and applying the electrode material according to a pattern, and electrode material controlling the number of grain boundaries present in the can to have a low-voltage characteristics and safety with respect to surge voltage, such as a chip varistor, it is possible to compact produced according to the grain structure of the varistor.
