NTC Thermistor 103 (10KΩ)

The NTC Thermistor 103 is a 10KΩ Negative Temperature Coefficient (NTC) temperature sensor whose resistance decreases as the temperature increases. It is widely used for temperature sensing, temperature compensation, battery packs, home appliances, and Arduino-based projects. The 103 marking indicates a nominal resistance of 10kΩ at 25°C.
