Description High-energy thermistor, this board failure is often due to the "sacrificial" destruction of the thermistor used to protect the circuit from high voltage and high current surges that could occur after a lighting strike during thunderstorms or other power surge. Features - Color: Black. - Material: Synthetic membrane. - Size: 4.50 x 1.50 x 0.30cm/ 1.77 x 0.59 x 0.12 inch. - Rated power: 0.125W. - The thermistor will protect against a higher energy surge. A cost-effective way of limiting the inrush of current that can damage other components. - In a switching power supply and other devices when the equipment is turned on. - The thermistor is small size and it is easy to install and use. - The thermistor is designed to protect equipments against transient voltage spikes. - The thermistor protects the circuit on start-up, providing a relatively high resistance at ambient temperature to limit inrush current. Package list: 20 x thermal resistors
