The EPCOS (TDK) S20K130E3K1 is a varistor, a voltage-dependent resistor (VDR) used for safeguarding electronic circuits against transient voltage surges, such as those resulting from inductive switching, electrostatic discharge (ESD), or lightning. By behaving as a voltage-regulated switch, varistors deliver increased resistance when running at regular operating voltages and lower resistance when the surge voltage goes beyond a particular limit. This process redirects extra current away from vulnerable components.

Applications

• Power Supplies: Offers defense against voltage surges originating from AC lines inside power supplies.
• Consumer Electronics: Used to safeguard delicate electronic parts found in computers, televisions, and various consumer devices.
• Industrial Equipment: Delivers security against voltage transients impacting control systems, industrial motor drives, and other industrial electronics.
• Telecommunications Equipment: Protects communication lines and machinery from lightning strikes and other forms of voltage surge.
• Automotive Electronics: Protects against voltage spikes within the electrical systems of vehicles, inside automotive electronic configurations.

Features

• High Surge Current Capability: Provides robust security by withstanding large surge currents without getting damaged.
• Fast Response Time: Redirects surge currents and reacts swiftly to voltage transients, reducing the potential for component damage.
