PTC stands for Positive Temperature Coefficient in English, which means positive temperature coefficient. Its resistance increases with temperature.
At the beginning of operation, PTC thermistor has a surge current, which can be seen from its current time characteristics (as shown in Figure 2).
Product applications: Load switch PWM application power management
Product applications: Battery protection, load switch, uninterruptible power supply
Product applications: Load switch PWM application power management
By applying a PTC thermistor to the electronic ballast of energy-saving lamps, the product can be directly connected across the resonant capacitor of the lamp tube without modifying the circuit.
