  • PTC Thermistor Brief Introduction
    The MZ12 series PTC thermistor represents a revolutionary breakthrough in green illumination appliances. As a state-of-the-art thermal resistor, this PTC thermistor offers an intelligent preheat start for electronic ballasts and energy-saving lamps without increasing temperature or consuming additional power post-preheat. This innovative technology significantly extends the on-off time and lifespan of lighting solutions, making it an indispensable component in modern energy-efficient lighting systems.

    Technical drawing showing the dimensions of a PTC thermistor used for intelligent preheat starting in electronic ballasts and energy-saving lamps.


    Working principle of PTC thermistor:
    When the high frequency shaking circuit loop has been put through, because PTC is in a cold state and Rt is in a
    low state of resistance, its resistance value is far lower than that of C2, and the light pressure is smaller than
    that of starting it. Then current through C1, RT forms the loop circuit-preheating filament. Meanwhile, PTC Thermistor
    is heated to above the Curie temperature, Rt heating temperature exceeding the switch temperature TSW and leaping to the state of high resistance too. Its resistance value is far higher than that of C2, and the current goes through C1, C2, forming the return circuit and causing LC resonance and producing high pressure and lighting the tube.
    To a certain electronic ballast,energy saving lights,higher PTC thermistor resistance,smaller PTC ceramic body dimension,lower switch temperature,will lead to its lower power consumption,shorter preheating time,conversly,larger power consumption,longer preheating time.Generally speaking, to delay the preheating time, we should select the relatively lower resistance, taller Tc point and bigger PTC Thermistor.

    Filament material will be sputtered seriously if the filament of energy-saving lamps starting with high voltage without preheating anymore,cause lamp tubes black and scrap in advance! Use PTC thermistors MZ12 type, the filament will be preheated around 1 second in starting, and then add high voltage to lit the lamp, can prevent black of the tube ends effectively,can also prevent components of lamps and lanterns lines such as audion from impact of starting instant large current and high back voltage,can prolong lamp life 10 times more.

    Advantages of Using Our PTC Thermistor
    1. Reliability and Efficiency: This thermal resistor does not increase power consumption after preheating, ensuring efficiency and reliability.
    2. Extended Lamp Life: By minimizing the thermal and electrical stress on the lamps during startup, the MZ12 PTC thermistor can prolong the life of lamps by up to ten times.
    3. High Switching Capability: With a switching capability of over 100,000 cycles, the MZ12 thermistor PTC ensures longevity and performance.
    4.Resistance stabilization:Resistance of PTC Thermistor doesn’t drift in normal temperature
    5.Environmental Compliance: Fully RoHS-compatible, our PTC thermistors are designed with environmental safety in mind.

    Guidelines for Choosing the Right PTC Thermistor
    Selecting the appropriate PTC thermistor involves considering several factors to ensure optimal performance and compatibility:
    – Curie Temperature: Ideal Curie temperature should be over 100°C to accommodate the high operating temperatures of energy-saving lamps.
    – Voltage Requirements: For circuits with a single capacitor, the PTC thermistor should withstand voltages typically above 800V.
    – High-resistance thermistor PTC offer enhanced reliability for startup applications;
    – Must consider in low-temperature start, at low temperatures, the PTC thermistor heat balance resistance relatively low, may cause tubes don’t start;
    – PTC thermistor switch life over 100000 times is much better;
    – Preheat time of PTC resistor can’t less than 0.4 seconds;
    – Phe power consumption of PTC thermistor need conform to the relevant provisions.
