Temperature Sensors - PTC Thermistors

PTC thermistors, or Positive Temperature Coefficient thermistors, are electronic components with a dependence of its electrical resistance on temperature. They can be used as current-limiting or over-current protection devices, temperature sensors, or fixed temperature switch components. The TFPT1206L4701KM is a PTC thermistor designed to be used as a temperature sensor in a wide range of applications.

Application Field

The TFPT1206L4701KM is a surface-mountable PTC thermistor, designed for use as a temperature sensor in consumer electronics and other industrial applications. It is widely used in regulating temperature in electric ovens, medical equipment, switches, fans, control boards, and other applications. This thermistor is designed to be soldered onto a printed circuit board (PCB) and does not require any special tools or fixtures. It is also small in size, allowing it to be used in cramped spaces where other components might not fit.

Working Principle

The TFPT1206L4701KM PTC thermistor works on the principle of changing resistance with temperature. When heated, the electrical resistance of the component increases, allowing the device to act as an over-current or temperature limiting component. When the temperature reaches a certain point, the device will stop conducting electrical current, thereby protecting the device from overheating or over current. This thermistor can also be used as a temperature sensor, with the resistance of the component changing in response to temperature changes.

The thermistor is made up of a ceramic composite material, with two lead wires of different length attached to it in order to detect the change in resistance. The longer lead wire detects changes in temperature, while the shorter lead detects the resistance. Both leads are then connected to a circuit board, allowing the device to measure and detect changes in temperature. The device is also designed to be used in both dry and humid environments.

Conclusion

The TFPT1206L4701KM PTC thermistor is an ideal temperature sensing component in a number of electronic and industrial applications. Its small size ensures that it can be used in confined spaces, while its robust construction ensures that it can be used in both dry and humid conditions. Additionally, its ability to regulate temperature and act as an over-current or temperature-limiting component makes it a versatile component for a wide range of applications.
