产品简介
Product Profile
压敏电阻的本体是由氧化锌颗粒组成的矩阵结构。颗粒之间的晶
界类似双向 PN 结的电气特性，当低电压时，这些晶界处于高阻
抗状态，当电压高时，又会处于击穿状态，是一种非线性器件。。
The body of varistor is a matrix structure composed of zinc
oxide particles. The grain boundaries between particles are
similar to the electrical characteristics of bidirectional PN
junctions. When the voltage is low, these grain boundaries are
in the high impedance state, and when the voltage is high, they
will be in the breakdown state, which is a kind of non-linear
device.
