Temperature sensors, also known as thermistors, are precision devices used to measure the temperature of a body or substance in different applications. Their most common form is a type of resistor whose resistance changes significantly with temperature. One such type is the PTC (positive temperature coefficient) thermistor, of which the PTFT0805L1002JW is an example. This article will explain its application field and working principle.

Application Field

PTC thermistors, such as the PTFT0805L1002JW, are suitable for use in a wide variety of applications including automotive electronics, consumer electronics, power supplies, inverters, and air conditioners. They are also widely used in temperature monitoring and overheat protection applications. The PTFT0805L1002JW is particularly suitable for use in high-temperature applications due to its high glass transition temperature. It is also suitable for use in temperature control systems that require a high degree of accuracy. The PTFT0805L1002JW can be used as a control device to regulate temperature within an acceptable range.

Working Principle

The PTFT0805L1002JW is a PTC thermistor with a glass encapsulated construction. It consists of a small ceramic disc covered with a film of metal oxide, which is the resistive element. When heated, the metal oxide layer expands and the resistance of the thermistor increases. When cooled, the resistance decreases. As the temperature changes, the resistance of the thermistor will also change accordingly. The thermistor can measure temperatures ranging from -30°C to +350°C, which makes it suitable for many applications.

The PTFT0805L1002JW is designed to be used in combination with an external voltage source or a signal conditioner. The signal conditioner can be used to convert the thermistor’s output signal into a readable voltage signal or a digital signal. The conditioning circuit can also be used to enhance the signal’s accuracy and resolution if necessary.

The PTFT0805L1002JW is an ideal temperature sensing device for a variety of applications. Its resistance versus temperature characteristics provide a high degree of accuracy and stability, which makes it suitable for use in sophisticated temperature control systems. Its compact size and low cost also make it an attractive option for many applications.
