330 OHM 30% 75 Deg 500V MZ11A Filament Preheating Ceramic PTC Thermistors

A. The Applications Of MZ11A PTC thermistors
It can be applied in the electronic ballast of kinds of luorescent lamps and electronic energy-saving lamps. No necessity to modify the circuitry.I proper thermistor is parallelconnected on the two ends of resonant capacitor ot lamps,cold startup of electronic ballast and elec-tronic energy-saving lamps will urn into the Preheatstartup which can make the Preheatingtime reach 0.4-2S and extend the life of service to three times of the primary.
B. Features Of the ceramic PTC Thermistor
1.Execution tlizing the characterstic of PTC material.
2.Smallsize of product.
3.High voltag resistance.
4.Longevity of service.
5.Low power when normally working.
