Brand Story.png


Inrush Current Limiting NTC Thermistor is a temperature sensitive resistor made of special semiconductor ceramic material with Negative Temperature Coefficient characteristics. They have a higher resistance value at room temperature. When they are energized, the temperature of the resistor body increases due to self-heating, and the resistance value decreases. Using this feature, they are used as Inrush current limiting/protection components for electrical and electronic equipment. These devices can easily and effectively limit abnormal currents, including surge currents when energized. Inrush Current Limiting NTC Thermistors used as current protection devices are also called power thermistors.
