Temperature Sensors - PTC Thermistors

PTC (positive temperature coefficient) thermistors are a type of temperature sensors that offer superior accuracy, reliable operation, and fast response times compared to other temperature measurement solutions. As its name implies, the resistance of a PTC thermistor increases with temperature. The TFPT0805L2701FZ is one of the most commonly used PTC thermistors, and can be seen in numerous industries. This article will cover the application fields and working principles of the TFPT0805L2701FZ.

Application Field

The TFPT0805L2701FZ is often used in automotive, industrial, consumer, medical, and energy applications. This thermistor is often chosen because it can operate over a wide temperature range (from -40°C to 125°C). It is also extremely durable and vibration-resistant, making it ideal for applications with continuously fluctuating temperatures and environments. Most commonly, the TFPT0805L2701FZ is used in temperature sensing and protection circuits. It can also be used in heater/cooler control, variable rate cooling/heating systems, and engine exhaust systems.

Working Principle

A PTC thermistor is a temperature sensitive resistor that works on a simple principle; when the temperature rises, the resistance of the thermistor increases. This increase in resistance is due to the semiconductor material used in its construction and the changing carrier mobility of the electrons. It should be noted that the thermistors resistance increases exponentially with temperature, rather than linearly. The TFPT0805L2701FZ is able to resist sudden voltage surges and has a low self-heating feature. This makes it a great option for temperature protection circuits.

The TFPT0805L2701FZ is a robust and reliable temperature sensor. It is capable of working over a wide temperature range, is vibration-resistant, and has a low self-heating feature. It is often found in automotive, industrial, consumer, medical, and energy applications and can be used in temperature sensing and protection circuits, heater/cooler control systems, variable rate cooling/heating systems, and engine exhaust systems. The working principle of a PTC thermistor is simple; when the temperature rises, the resistance of the thermistor increases.
