Time Delay Starting PTC Thermistor

A typical application of switching PTC thermistor is the preheating of electrode in energy-saving lamps or fluorescent lamps. Switching PTC can also be used as a power resistor for loading a capacitor, for example in power supplies or in control units of production equipment.
As the preheating and softly-starting component of the electronic ballasts and energy-saving lamps, the PTC thermistor can greatly increase the light switching and opeating time.
Meanwhile, it can overcome the disadvantage of temperature-rising after preheating and starting of the electronic ballasts and energy-saving lamps, therefore it can be considered as another breakthrough revolution of green illumination electric appliances.
The PTC can be connected across the lamp resonator without changing the circuits. It can change hard start of the ballast and electronic energy-saving lamp to preheated start and the preheating time of the filament can come up to 0.4-2 seconds, which will extend the service life of the fluorescent tube by over 10 times.
