■H 系列压敏电阻器 H Series Varistor 

氧化锌压敏电阻器是以氧化锌为主要材料制造的半导体无极性电子陶瓷元件。当施加在压敏电 阻器两端的电压达到某一阀值时，压敏电阻器的电阻值迅猛变小，从而在电子（电力）线路上起降 压作用，达到保护其它元器件的目的。 Zinc Oxide Varistor are non-linear resistors utilizing semiconductor ceramic element which mainly composed of zinc oxide. When the applied voltage on both termination reach the surge value, the voltage of electronic circuit would be reduced to protect the other components.
