压敏电阻是一种具有非线性伏安特性的特殊电阻器件，英文名称叫Voltage Dependent Resistor，简写为VDR ，或者叫做Varistor。 压敏电阻不是真正的电阻，而是一种具有 瞬态电压抑制 功能的元件，一般无正负极之分，这一点不同于 TVS ，使用时同样是并接与被保护IC或 ...

This MOV is suitable for 220V AC line protection in a typical electronic devices against voltage surges and spikes, such as those generated by inductive switching transients. Many users ask us that MOV says marking as 470V so how is it suitable for 220V application.

压敏电阻器简称VDR，是一种对电压敏感的非线性过电压保护半导体元件。 当加在压敏电阻上的电压低于它的阈值时，流过它的电流极小，它相当于一个阻值无穷大的电阻。 也就是说，当加在它上面的电压低于其阈值时，它相当于一个断开状态的开关。 当加在压敏电阻上的电压超过它的阈值时，流过它的电流激增，它相当于阻值无穷小的电阻。 也就是说，当加在它上面的电压高于其阈值时，它相当于一个闭合状态的开关。 选用压敏电阻器前，应先了解以下相关技术参数：标称电 …
