压敏电阻 (Metal Oxide Varistor (MOV))
■金属氧化物压敏电阻(MOV)是以氧化锌(ZnO)为主要成分的非线性电阻元件,该元件浪涌电流耐量及非线性系数非常大,在阈值电压以下时,电阻非常高,几乎没有电流流过,如果超过该阈值电压,电阻急剧降低,可以泄放大电流;由于这种特性,作为电子、电气设备的保护元件,对异常电压的吸收,雷击浪涌的吸收等发挥着很大的作用。
■赛尔特公司的压敏电阻具有高通流密度、低限制电压、良好的交流耐受能力,同时可以根据客户要求定制。

■Metal Oxide Varistor (MOV) as one nonlinear resistance element is mainly made of zinc oxide (ZnO), which has very high surge capacity and big nonlinear coefficient. Below the threshold voltage, its resistance is very high, nearly no current flows through, but above the threshold voltage, the resistance reduces sharply, huge current can be discharged. Due to this characteristic, Varistor as a protection component in electronic and electrical equipment can absorb abnormal over-voltage and lightning surge.
■SETsafe | SETfuse Varistor is with High Surge Current Density, Low Clamping Voltage,and Good Surge Capacity. It can also be customized as required.
