Temperature Sensors - PTC Thermistors

PTC thermistors are temperature sensors made up of semiconductor materials that exhibit a positive temperature coefficient. The TFPT1206L1000DV thermistor is a specific type of PTC thermistor. It has a maximum working temperature of 250°C, a positive temperature coefficient of 6 mW/°C, and a breakdown voltage of 35 V. It is widely used in many applications for temperature control and sensing.

TFPT1206L1000DV Application Field

The TFPT1206L1000DV thermistor is mainly used in temperature sensing and control applications, including temperature regulation, temperature detection, over-temperature protection, and thermal management in office equipment, home appliances, industrial equipment, etc.It is also suitable for high-temperature applications, such as motor and vehicle controls to provide high precision temperature control. Other potential applications include laser welding machines, ovens and other industrial applications, and circuit protection systems.

Working Principle

The working principle of a PTC thermistor is based on the variation of its electrical resistance with temperature. The resistance of the TFPT1206L1000DV thermistor increases with temperature, otherwise known as its positive temperature coefficient. The resistance of the thermistor rises as temperature increases, and this increase can be used to measure temperature.When current passes through the thermistor, it generates resistive heating due to its positive temperature coefficient. This heat causes the thermistor to increase its resistance, which then increases the voltage drop across the thermistor. This change in resistance is recorded and used to measure the temperature.The thermistor\'s resistance also enables it to be used as a protective device; once the temperature reaches a certain threshold, the thermistor\'s resistance increases rapidly, restricting the flow of current. This stops the system from overheating and ensures reliability and safety.

Conclusion

The TFPT1206L1000DV thermistor is a type of PTC thermistor that is designed for sensing and temperature regulation applications. It has a maximum working temperature of 250°C, a positive temperature coefficient of 6 mW/°C, and a breakdown voltage of 35 V. Its applications range from motor and vehicle controls to laser welding machines, ovens and other industrial applications, and circuit protection systems. The working principle of the thermistor is based on the variation of its electrical resistance with temperature; as the temperature increases, so does the resistance of the thermistor. This change in resistance can then be used to measure the temperature.
