Additional Details:

The S07K550E2 varistor has a maximum allowable voltage of 550V. The 'E2' suffix indicates an epoxy coating for enhanced insulation. These varistors operate by exhibiting a non-linear resistance; when the voltage exceeds a certain threshold (clamping voltage), the resistance rapidly decreases, diverting the surge current away from the protected circuitry. Consult the official EPCOS (TDK) datasheet for detailed technical specifications, including surge current ratings, clamping voltage characteristics, and temperature derating information.
