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.
