High Temperature And High Humidity Performance SMD Metal Oxide Varistor Strong FOR LED Circuit Protection
SMD MOV Varistor.pdf
SMD varistors can be regarded as a kind of variable resistors, which are usually used in parallel in the circuit. When working in a circuit, since the varistor has a high impedance, its leakage current will be very small, which can be regarded as an open circuit state, and basically has no effect on the circuit. However, when a high surge voltage suddenly occurs in the circuit, the resistance value of the varistor will decrease immediately. Generally speaking, the structure of the varistor can be reduced from the megohm level to the milliohm level. Due to this change, The current value allowed to flow through it is very large, and the voltage will be stabilized at a certain value range at this moment. However, since the surge voltage peak withstand capacity of the varistor also depends on its package size, there will be different surge current values.
