NTC Inrush Current Limiter

If circuits consist of capacitor, bulb filament, heater, or inverter for fluorescent lamp, they will produce a inrush current (10~100 times greater than a normal operating current) at the moment of switch’s turn-on. Zero-power resistance of NTC thermistor limits the inrush current during initial turn-on, and then heats up the thermistor following continuous flow of current. The thermistor’s resistance is reduced to a very low level and allows operating current to flow during normal operation.
