Temperature Sensors – PTC Thermistors are devices that are commonly used to monitor and control temperature in various applications. PTC Thermistors are precision resistors that are constructed with a polycrystalline ceramic between two electrodes. The ceramic material is a positive temperature coefficient type of material, which means that as the temperature increases, the resistance of the thermistor increases as well. The TFPT0805L3901FV is an example of a PTC thermistor. It has a very low thermal resistance and is ideal for applications such as over temperature protection.

This PTC thermistor has a resistance range of 3900Ω to 11000Ω at 25°C. It also has a positive temperature coefficient of 0.39%, which means that the increase in resistance as the temperature increase is small and precise. This makes the TFPT0805L3901FV an ideal choice for controlling and monitoring temperatures in accuracy demanding applications.

The working principle of a PTC thermistor is simple. It is made up of two terminals of different materials, with a sensitive ceramic material in between them. As the temperature increases the Ceramic material expands, causing an increase in resistance. The change in resistance is usually in the form of a curve, which is virtually linear. This means that it is relatively easy to calculate the temperature based on the measured resistance values.

The TFPT0805L3901FV PCT thermistor is most suitable for applications that require reliable temperature control and monitoring. It can be used to detect temperature thresholds in various devices and systems, and also to monitor temperature in both indoor and outdoor environments. It can be found in various applications such as temperature control systems for medical equipment, power supplies, HVAC systems and data centres.

In conclusion, the TFPT0805L3901FV PCT thermistor is an ideal choice for accurate temperature detection and control. It has a reliable and low thermal resistance which makes it suitable for accuracy demanding applications. The working principle of the thermistor is relatively simple and easy to measure, and it can be used in a variety of applications.
