Temperature sensing technology largely determines the reliability of temperature-related products in industries such as automotive, consumer electronics, medical, robotics, and aerospace. Enabling the technology are temperature sensors, which measure temperature and convert the signal to an output. Over the years, a variety of temperature sensing methods have been developed, one of which is the Positive Temperature Coefficient Thermistor (PTC Thermistor). This article will discuss the TFPT1206L6800FV application field and working principle in the context of PTC thermistors.

Positive Temperature Coefficient (PTC) thermistors are temperature-dependent resistors that display a sharp increase in resistance when the ambient temperature exceeds a certain point. This property enables these thermistors to serve as self-regulating heaters, switches, current limiters, and current interrupters. They have been widely used in protecting relay systems, over-current protectors, and circuit breakers. The TFPT1206L6800FV is a PTC thermistor developed by TDK.

The TFPT1206L6800FV is a thin film polymer PTC thermistor that features an operating temperature range of -40°C to 130°C. The thermistor module has a nominal resistance of 680 ohms and a maximum current rating of 8 A at 25°C. The thermistor has a power dissipation capability of 1.6 W and it can be used in both low-temperature and high-temperature installations. Its self-regulating properties enable the thermistor to improve the safety and performance of a wide variety of devices and systems.

The TFPT1206L6800FV has good resistance characteristics from 25°C to 130°C, and it can quickly detect changes in temperature. The thermistor\'s resistance increases with rising temperature, creating a positive feedback loop that effectively limits further temperature increases. This self-regulating property helps minimize damages caused by excessively high temperatures.

The TFPT1206L6800FV can be used in a variety of applications. It can be used as a temperature sensor in home appliances, such as air conditioners, refrigerators, and water heaters. It can also be used in automotive systems, such as in engine cooling systems, as well as in industrial equipment and power tools. Additionally, the thermistor can be used in photovoltaic (PV) systems, for temperature compensation, and in LED lighting systems.

The TFPT1206L6800FV thermistor functions by detecting the increase in temperature and responding by creating a positive feedback loop. It does this by increasing its own resistance, which limits further temperature increases. With its narrow temperature range and fast reaction time, the thermistor can protect devices and systems against excessive heating. By Self-regulating itself, this PTC thermistor helps ensure the reliability and safety of temperature-sensitive products.
