Results for tag: "Varistor"

A Varistor is an electrical switch used to protect circuits from overvoltage. It is a voltage-dependent resistor that can be used to limit the voltage applied to a circuit. It is typically used in power supplies, motor control circuits, and other applications where overvoltage protection is needed. Varistors are available in a variety of sizes and shapes, and can be used in both AC and DC circuits. Varistors are typically made from a ceramic material, and are designed to absorb excess voltage and dissipate it as heat. They are also used to protect against surges and spikes in voltage, and can be used in combination with other components to provide additional protection. The Varistor market is highly competitive, with a wide range of manufacturers offering products for a variety of applications. Companies in the market include Littelfuse, Bourns, Vishay, Eaton, and ABB. Show Less Read more
