Additional Details:

The S10K115 has a varistor voltage of 115V. Its surge current capability, clamping voltage, and other electrical characteristics are detailed in the product datasheet. It is typically a leaded disc varistor designed for through-hole mounting. The specific dimensions and lead configuration are also available in the datasheet.

Varistors are non-linear resistors that exhibit a significant decrease in resistance when the voltage across them exceeds a certain threshold. This allows them to divert excess current away from sensitive components, providing effective surge protection. The S10K115 is designed for repetitive surges and provides reliable overvoltage protection for various electronic applications.
