Additional Details:

The S10K250G5 has a varistor voltage of 250V. The 'G5' designation likely refers to a specific tolerance or packaging characteristic. Detailed electrical characteristics such as maximum surge current, clamping voltage, and energy handling capability can be found in the product datasheet. It is typically a ceramic disc varistor with radial leads for through-hole mounting.

Varistors are voltage-dependent resistors that exhibit a significant decrease in resistance when the voltage exceeds a certain threshold. This allows them to shunt excess current away from sensitive components, protecting them from damage. The S10K250G5 is designed to handle repetitive surges and provide reliable overvoltage protection in a wide range of applications.
