Product Details
Product Overview
Conventional varistors use silver as the electrode material. Silver, being a precious metal, results in high electrode material costs. Therefore, using copper as the electrode material can significantly reduce production costs.
Copper, as a base metal, has conductivity second only to silver, and its price is far lower than silver. Therefore, using copper paste to replace silver paste, and achieving the performance of silver, can reduce the cost for varistor manufacturers.
