WMZ11A PTC thermistor

Article source:admin Popularity:Published time:2019-07-30 17:54

1. Scope of application:
WMZ11A PTC thermistor is used in various fluorescent electronic ballasts and electronic energy-saving lamps without changing the wiring. The appropriate thermistor can be directly connected across the resonant capacitor of the lamp tube, and the hard start of the electronic ballast and the electronic energy-saving lamp can be changed to be a warm-up start. Allowing the filament to warm up for 0.4 to 2 seconds can extend the life of the lamp by more than three times.
2. Features:
WMZ11A PTC thermistor is made of PTC characteristics of materials. It has small volume, high withstand voltage, long life and low power consumption during normal operation.
3. Application principle:
    The WMZ11A PTC thermistor uses the PTC thermistor to achieve the warm-up startup principle as shown on the right: When the switch is just turned on, R t is in the normal temperature state, its resistance value is far lower than the C 2 resistance value, and the current jumps into the high resistance state through the C 1 , R t self-heating temperature exceeding the Curie point temperature T c . Its resistance is much higher than the value of C 2 , and the current forms a loop through C 1 and C 2 to cause LC resonance, which produces a high-voltage lighting lamp.
