Temperature Sensors - PTC Thermistors are used to measure the temperature of an environment. They do this by utilizing a negative temperature coefficient (NTC). In an NTC thermistor, the resistance decreases as the temperature increases. This is opposed to the traditional models with a Positive Temperature Coefficient (PTC), where the resistance increases as the temperature increases.

The PTFT0805L1000JW is a particular type of PTC thermistor. It is a surface mount device and stands for the physical dimensions of 0805 (8.0mm x 5.0mm). The “L” refers to the lead pitch, which is 1.25 mm, and the “1000J W” refers to the resistance of 1000 ohms, and the tolerance is 0.1%.

The PTFT0805L1000JW has many uses in industrial applications, such as:

• Temperature control systems
• Overload protection devices
• High power switching circuits

Working Principle

The PTFT0805L1000JW PTC thermistor works by a change in electrical resistance according to the changes in temperature. When the temperature increases, the resistance decreases in a predictable and reliable manner. This enables it to be used as a temperature sensor, as well as in other applications such as high power switching circuits and overload protection devices.

The resistance value of the PTFT0805L1000JW is determined by three key factors. These are the area of the device, its thickness and the temperature coefficient of resistance (TCR). This device has an area of 8.0mm x 5.0mm, a thickness of 0.6 mm and a standard TCR of 30ppm/K. The TCR defines the rate of change in resistance as the temperature changes, and can be used to gain insights into the performance of the device under different temperature conditions.

The PTFT0805L1000JW is an excellent choice for an accurate reading of a room or system\'s temperature. The device\'s small size, ease of integration and reasonable cost makes it one of the most widely used PTC thermistors in the industry.

In summary, the PTFT0805L1000JW is a PTC thermistor suitable for industrial application use, with an accuracy of temperature sensing. It is a surface mount device and is very reasonably priced for the quality of its operation. It is easy to integrate into other applications such as temperature control systems, overload protection and high power switching circuits. Its small size and high degree of accuracy make it an excellent choice for many temperature sensing applications.
