Temperature Sensors – PTC ThermistorsPTC thermistors are thermally-sensitive resistor devices that are used to measure and control temperature. They are commonly used in a range of applications such as temperature sensing, current sensing, voltage regulation, and overcurrent protection. In particular, the TFPT0805L8200FY is a popular PTC thermistor for use in electronic devices. This article will discuss the application field and working principle of a TFPT0805L8200FY PTC thermistor.The TFPT0805L8200FY is a PTC thermistor that is designed for surface-mount applications. It has excellent accuracy and reliability, and is designed to withstand both high and low temperatures. The PTC thermistor is able to measure temperatures from 0°C to +85°C, and has a temperature coefficient of resistance (TCR) of -70 ppm/°C. This allows the device to be used for accurate measurement of temperature in a wide variety of environments.The TFPT0805L8200FY has a number of advantages over other PTC thermistors. Firstly, it has a very low self-heating property, which means it requires less power to operate. This makes it ideal for applications in which power consumption is a critical factor. Additionally, it has a fairly low TCR, which allows for more precise temperature measurements. Finally, the PTC thermistor has excellent resistance to thermal cycling, making it suitable for a wide range of applications.The working principle of a PTC thermistor is based on what is known as the Peltier-Seebeck effect. This effect occurs when there is a difference in temperature between two sides of the device. When a current is applied to the PTC thermistor, it produces a voltage that is proportional to the difference in temperature. This voltage can then be used to measure and control the temperature of a device or system.In addition to temperature measurement, the TFPT0805L8200FY PTC thermistor can also be used for other applications such as current sensing, voltage regulation, and overcurrent protection. For example, the device can be used to detect if the current in a circuit is too high or if the voltage is too low. When this is detected, it can then be used to automatically disconnect the circuit and prevent any further damage.In conclusion, the TFPT0805L8200FY PTC thermistor is an ideal device for temperature measurement, current sensing, voltage regulation, and overcurrent protection. It has excellent accuracy and reliability, and is able to operate in a wide range of environments. Additionally, the PTC thermistor is able to measure temperatures from 0°C to +85°C, and has a highly precise TCR. Finally, it has a low self-heating property, making it suitable for applications that require low power consumption.
