Vishay Cross Silicon Coating PTC Thermistor MZ5 105C 300R 265V For
I Description Of The Vishay Cross Silicon Coating PTC Thermistor
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 Ampfort Electronics covers the entire
series from 3 watts to 85 watts, and can develop special
specifications of PTC thermistors according to customer

temperature start heater, fuel heater, honeycomb heater, fuel level
indicator, engine cooling water temperature detection table
IV OPERATING PRINCIPLE Of The Vishay Cross Silicon Coating PTC Thermistor MZ5
See Fig.1: Immediately after power is switched on, the PTCR is cold
and it's resistance is far lower than C2's.
The current through C1 and Rt forms a return circuit to preheat the
filament. About 0.4-2s later,
Rt's joule heat temperature exceeds Curie point Tc and the PTCR
will switch. Its resistance is far higher than C2's.
The current passes through C1 and C2 to form a return circuit,
which causes LC resonance and produces high
voltage to light the fluorescent tube.
