Temperature sensors, such as PTC thermistors, are important components for most electronic applications. The TFPT0805L1201DV is a small temperature sensing device that features an active PTC thermistor with a wide temperature measurement range, from -40°C to +125°C, and a high resistance accuracy between -40°C and +125°C, of +/- 0.2°C.

The TFPT0805L1201DV is a two-pin device with an operating temperature range between -40°C and +125°C, with Resistance at 25°C of 8.1Kohms, and a nominal Beta of 3650K. It is a surface mount device, in an 805 size package, with a maximum leakage current of 9uA, and a maximum power dissipation of 10mW. The TFPT0805L1201DV is available in the small packages of 0805 and 1206 surface mount, allowing for a range of temperature sensing applications.

The TFPT0805L1201DV is a passive temperature sensor which contains a organic semiconductor-based PTC thermistor, with resistance varying with the temperature, and is mainly used for temperature sensing. This convenient device senses the ambient temperature by using a developed multilayer structure based on an organic semiconductor and the metal-oxide interface layer to detect the negative temperature coefficient of the PTC thermistor. This device is ideal for applications ranging from consumer electronics to automotive, AC/DC adapters, and telecoms.

The working principle of the PTC thermistor employed in the TFPT0805L1201DV is based on the phenomenon of positive temperature coefficient (PTC). In a PTC thermistor, as the temperature increases from the ambient conditions, the resistance also increases exponentially. The PTC thermistors use a range of organic polymers and semiconductors to create resistance temperature curves which accurately measure temperature. The resistance of a PTC thermistor is measured and the temperature is calculated from this measured resistance. The PTC thermistors use the heat that is created by the resistance changes in their circuits in order to sense the ambient temperature.

The TFPT0805L1201DV is a great choice when it comes to small and compact temperature sensing applications. Its wide temperature range and high resistance accuracy make it well suited for a variety of temperature sensing applications. Its small size and flexibility make it an ideal choice for applications such as automotive, AC/DC adapters, consumer electronics, and telecoms.
