300R 5mm PTC Positive Temperature Coefficient Lamp Starting PTC Type Thermistor
SPMZC Intelligent PTCR PTC Thermistor 300R 105C 290V For Energy Saving Lamp Starting
I Description Of The SPMZC Intelligent PTCR PTC Thermistor
Sensors and components need keep improving with the demands of markets for higher and higher quality products. Our company introduced patent producing technology of intelligent PTCR to produce preheating-starting components of electronic ballasts and electronic energy-saving lamps ,which enormously increase the number of switching cycles and life of fluorescent lamps .At the same time ,they overcome temperature warmuping and energy wasting of normal PTCR after they preheated and started electronic ballasts or electronic energy-saving lamps. They enhance luminous flux ,lumen numbers and luminescence efficiency,so they are called another creative revolution of green illuminance electricities.
II Features Of The SPMZC Intelligent PTCR PTC Thermistor
1. PTC and varistor composite;
2. No heat and no power consumption after the filament is warmed up;
3. Small size for easy installation;
4. Operating temperature range: -40 -- +125℃(V=Vmax);
