S10K300 Varistor

The S10K300 Varistor is a lead-free, RoHS-compliant metal-oxide varistor designed to provide transient voltage suppression and surge protection for single-circuit applications. Engineered for reliable clamping performance, this disc-style varistor is suitable for systems requiring robust energy absorption and high surge current capability.

Key electrical ratings include a varistor nominal voltage of 470V, an energy absorption rating of 47 joules, and a surge current capability of 2.5kA. The compact 10mm disc package enables integration in constrained board spaces while maintaining the thermal and electrical characteristics necessary for transient suppression. The component is specified for a maximum of 300VAC and 385VDC continuous voltages and is intended for use in single-circuit protection roles where compliance with lead-free and RoHS requirements is needed.
