The S20K460E2K1 is a varistor manufactured by EPCOS (TDK), engineered to provide robust overvoltage protection for electronic circuits and equipment. Varistors are voltage-dependent resistors characterized by their high resistance at normal operating voltages and a rapid decrease in resistance when subjected to high-voltage transients. This characteristic allows them to effectively clamp the voltage and divert surge currents away from sensitive electronic components, preventing damage.

Applications

• Power distribution systems: Protecting electrical panels and branch circuits from voltage surges.
• Industrial control systems: Safeguarding PLCs, motor drives, and other sensitive control equipment.
• Consumer electronics: Providing surge protection for appliances such as televisions, computers, and audio equipment.
• Lighting systems: Protecting LED drivers and other lighting components from voltage transients.
• Automotive electronics: Protecting automotive control units and other electronic systems from voltage surges in the vehicle's electrical system.

Features

• High surge current capability: Designed to withstand high surge currents without degradation or failure.
• Fast response time: Provides rapid clamping of transient voltages to protect sensitive components.

Technical Specifications

The S20K460E2K1 varistor has a varistor voltage of 460V. The maximum surge current (8/20 µs pulse) it can withstand is typically around 6.0kA. The clamping voltage at this surge current level will be specified in the product datasheet. It is critical to consult the official EPCOS (TDK) datasheet for comprehensive electrical characteristics, mechanical dimensions, and safety certifications. The datasheet will also include the operating temperature range. The typical case size is a 20mm disc.
