what is a varistor

A varistor is a specialized electronic component that is designed to protect electrical circuits from excessive voltage fluctuations or surges. It acts as a voltage-sensitive resistor, changing its resistance in response to the applied voltage. The primary function of a varistor is to absorb and dissipate high-energy voltage spikes by diverting them away from sensitive electronic devices and preventing damage to the circuitry. It is commonly used in various applications such as power supplies, surge suppressors, voltage regulators, and lighting systems. Our varistors are built with the highest quality materials and are extensively tested to guarantee optimum performance and reliability.
