Temperature sensors are instruments used to measure temperature. PTC thermistors are a type of temperature sensor, which contains a semiconductor element containing positive temperature coefficients (PTC). TFPT0805L1801FZ is a PTC thermistor with NTC characteristic.

TFPT0805L1801FZ is a small PTC thermistor with a diameter of 0805, which is suitable for monitoring and controlling the temperature of the system. It is designed with a high heat resistance, and is capable of operating between -40°C and 150 °C.

TFPT0805L1801FZ is mainly used in electronic equipment and systems to detect temperature. It can be used in variable air volume (VAV) systems, by detecting changes in air temperature, and providing accurate air temperature control. It can also be used in HVAC systems to detect the temperature in both open and closed environments. In automotive applications, TFPT0805L1801FZ can be used to detect the temperature of engine coolant, facilitating better performance and fuel efficiency.

The working principle of TFPT0805L1801FZ is based on the positive temperature coefficient of resistance that operates when a voltage is applied. As the temperature increases, the resistance of the PTC thermistor increases as well, thus providing an indication of temperature. The sensitivity of the device is determined by the size and shape of the tantalum clips that contain the semiconductor element.

When using TFPT0805L1801FZ, it is important to ensure that the voltage is not too high, as this may damage the device. For a 0805 footprint, the output should be limited to 1.0-2.5V for safety.

In summary, TFPT0805L1801FZ is a small PTC thermistor used to measure temperature. It is commonly used in temperature control systems such as those used in HVAC and automotive applications. The working principle is based on the positive temperature coefficient of resistance that operates when a voltage is applied, resulting in an increase in resistance when the temperature increases. It is important to ensure that the voltage is not too high when using TFPT0805L1801FZ.
