AMWEI - Lighting Switching PTC Thermistor
Lighting Switching PTC Thermistor are used when a load in series with the PTC thermistor has to be switched off after a time delay and when switching occurs frequently. 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 ...
