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.

electronic circuits against transient overvoltages, such as
electrostatic discharges and surge
SMD Varistor Characteristic
SMD Varistor is a kind of the voltage sensitive resistor,
symmetrical volt-ampere characteristics, its value as the voltage
rises is nonlinear, when the voltage within a certain range to rise
further, the phenomenon of "short circuit" more intense.
