Electronic Ballast MZ5 105C PTC Thermistor 300R PTC Positive Temperature Coefficient

Vishay Cross Silicon Coating PTC Thermistor MZ5 105C 300R 265V For Electronic Ballast

I Description Of The Vishay Cross Silicon Coating PTC Thermistor MZ5

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 requirements.

II Application of PTC thermistor in circuit control and sensor

Transistor temperature compensation circuit, temperature measurement and temperature control circuit, overheat protection circuit, incubator, electric fan, color roll washing, kettle, electric water heater, electric blanket, fluorescent lamp, energy-saving lamp, battery charging, transformer winding, heater, delayer , Compressor, color TV, color display, over-current security, liquid level control, electronic ballast, program control switch, electronic component aging station

III Application of PTC thermistor in electric heating appliances

Heater, room heater, dryer (cabinet), tumble dryer, hand dryer, hair dryer, hair curler, steam beauty device, rice cooker, mosquito repellent, hand warmer, shoe dryer, pressure cooker, disinfection cabinet, coal Oil gasification furnace, electric iron, electric soldering iron, plastic welding gun, sealing machine

IIII Application of PTC thermistor in automobile

Electrical overload protection device, hybrid heater, low 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.
