10D431K Varistor

Description:

The 10D431K varistor is a type of voltage-dependent resistor designed to protect electronic circuits from transient voltage spikes and surges. It is commonly used as a component in surge protection devices and circuits to suppress high-energy transient events that could otherwise damage sensitive electronic components. The 10D431K varistor is characterized by its ability to rapidly change resistance in response to varying voltage levels, thereby diverting excess current away from the protected circuit and limiting voltage spikes to safe levels.
