The RD412ETTE101J is a leaded disc varistor manufactured by KOA Speer. These varistors are designed to protect electronic equipment from voltage surges and transients. They achieve this by providing a low impedance path to ground when a voltage surge exceeds a specific threshold, thereby clamping the voltage to a safe level and preventing damage to sensitive components.

Applications:

• Protection of power supplies from transient voltage spikes.
• Surge protection in consumer electronics.
• Suppression of inductive switching surges in motor controls.
• Protection of sensitive electronic components in industrial equipment.
• Use in telecommunications equipment for line surge protection.

Features:

• High surge current capability: The RD412ETTE101J is capable of withstanding high surge currents, making it suitable for applications where large voltage transients are expected.
• Quick response time: Varistors react almost instantaneously to voltage surges, providing rapid protection.
• Wide operating voltage range: These varistors can operate over a wide range of DC and AC voltages.
• Compact size: The disc-shaped package allows for easy integration into electronic circuits.
• RoHS compliant: These varistors are compliant with RoHS standards, ensuring they do not contain hazardous substances.
• High reliability: KOA Speer varistors are known for their reliability and long lifespan.

Benefits:

• Enhanced equipment reliability: By protecting sensitive components from voltage surges, the RD412ETTE101J helps to enhance the reliability and lifespan of electronic equipment.
• Reduced downtime: Protection against voltage transients minimizes the risk of equipment failure and downtime.
