一、 产品性能（CHARACTERISTIC DATA）
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 doth terminat
-ion reach the surge value, the voltage of electronic circu
-it would be reduced to protect the other components.
