Diameter 5mm 75C 300～500 Ohms (400R±25%) PTC Thermistor Power Supply, Ballast
MZ5 series PTC thermistors are used in all kinds of fluorescent lamp electronic ballasts and electronic energy-saving lamps. There is no need to change the circuit and the product is directly connected to the two ends of the resonant capacitor of the lamp tube, which can change the electronic ballast and electronic energy-saving lamp. The hard start is the preheating start, and the preheating time of the filament is 0.4~2 seconds, which can extend the life of the lamp more than 4 times.
The MZ5 series produced by Tianrui Electronics covers the entire series from 3 watts to 85 watts, and can develop special specifications of PTC thermistors according to customer requirements.
