Abstract
A method of manufacturing a metal oxide varistor (MOV), the method including placing a quantity of a MOV composition in a pressing die, the MOV composition including metal oxide granules mixed with a polyaniline-polymer, performing a pressing operation including operating the pressing die to compress the MOV composition into a solid MOV chip, and applying first and second electrodes to opposing first and second sides of the MOV chip, wherein the pressing operation is performed at a temperature in a range of 15 degrees Celsius to 200 degrees Celsius.
