MZ11A 330 OHM 500V Ceramic Filament Preheating PTC Thermistor

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

MZ11A Filament Preheating PTC Thermistor

1. Application

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.

2. Characteristics

Execution utilizing the characteristic of PTC material
Small size
High withstand voltage
Long life
Small power cost when normally workin
