Temperature Sensors - PTC Thermistors play a important role in detecting temperature and controlling hot spots, over-temperature conditions and temperature cycling. The TFPT0805L2701FV is a PTC thermistor typically used for temperature sensing and temperature control. This thermistor is mainly designed for surface mounting and can operate in an environment where the temperature range is -40°C to +125°C. It is suitable for applications such as power supplies and temperature control modules which can tolerate a maximum of 0.1 Ω resistance variation.

The TFPT0805L2701FV is a Negative Temperature Coefficient (NTC) thermistor. This means that its electrical resistance decreases with an increase of temperature and vice-versa. When the surrounding temperature rises, the thermistor’s resistance decreases, allowing more current to flow through the circuit. This current can be used to activate a relay or any other device to control the thermal condition of a system. Conversely, when the temperature decreases, the resistance of the thermistor increases, thereby reducing the current flow and stopping the circuit from activating.

The TFPT0805L2701FV features two connection points - one for a positive voltage and the other for ground. By applying a constant voltage, the thermistor uses the Sure Temperature Compensation circuit to keep the temperature coefficient hysteresis within 0.1Ω. This will help to ensure a reliable temperature sensing outcome.

The TFPT0805L2701FV can be designed to be used in a variety of applications such as automotive, appliance and industrial electronics. It is especially suitable for applications where the temperature range is -40°C to +125°C and high reliability is required. In automotive applications, the thermistor can be used to detect the engine temperature, controlling the cooling fan, air conditioning and other components. In appliances, it can be used to detect overheating or indicate the temperature with its LED indicator. For industrial electronics, it can be used in temperature control modules, and power supply protection systems.

Overall, the TFPT0805L2701FV is a reliable and accurate temperature sensing component. With its hysteresis of 0.1Ω and temperature range of -40°C to +125°C, it is a great choice for applications that require temperature sensing and control.
