Product Description

330 OHM 30% 75 Deg 500V PTC Thermistor Ceramic Overheating PTC Thermal Protection

Resettable Ceramic PTC Thermistor 330 OHM 30% 75Deg 500V For Overheating Protection

I Description Of The Resettable Ceramic PTC Thermistor 330 OHM

It can be applied in the electronic ballast of kinds of fluorescent lamps and electronic energy-saving lamps. No necessity to modify the circuitry. If proper thermistor is parallel connected on the two ends of resonant capacitor of lamps,cold startup of electronic ballast and electronic energy-saving lamps will turn into the preheat startup which can make the preheat time reach 0.4-2sec and extend the life of service to three times of the primary.
