Quantity:


The body of the varistor is a matrix structure composed of oxide particles. The grain boundary between the particles is similar to the electrical features of the bidirectional PN junction. When the voltage is low, these grain boundaries are in a high impedance state, when the voltage is high, they turn into the breakdown state. MOV is a nonlinear device.


Application: Consumer Electronic, telecommunication, Lighting, etc.
