PTFT0805L0030JW is a type of Positive Temperature Coefficient (PTC) thermistor which is a temperature sensor and an electrical component. PTC thermistors are resistors whose resistance will increase exponentially with an increase in temperature. Most PTC thermistors are used as over-temperature protection devices, having current limiting properties, which provide device protection against over-heating, thus ensuring reliability and safety. This article will discuss the application field and working principle of the PTFT0805L0030JW PTC thermistor.

PTC Thermistors - General Overview

PTC thermistors are solid state temperature sensing devices which have a positive temperature coefficient of resistance. This resistance increases as the temperature increases, allowing the device to act as a thermal switch, turning on when the maximum temperature has been reached. The temperature at which the switch turns on is known as the “trip point” and is typically adjustable. The increase in temperature can be caused by either internal or external heating sources, and the thermistors are normally used for protection in switching power supplies and other applications.

Application Field of the PTFT0805L0030JW PTC Thermistor

The PTFT0805L0030JW is a PTC thermistor designed for use in a wide variety of applications. It is particularly suited for use in low-voltage high-temperature DC protection circuits, as well as high-temperature switching applications. This PTC thermistor is ideal for use in automotive, computer, and home appliance applications, as it can provide reliable over-temperature protection for sensitive electronic components. The device also provides superior overall accuracy with tight temperature tolerances, making it an excellent choice for temperature control applications.

Working Principle of PTFT0805L0030JW

The PTC thermistor operates on the principle that the resistance changes exponentially with temperature. The resistance of the thermistor increases as the temperature increases due to the positive temperature coefficient of its semiconductor material. This allows the device to act as a thermal switch, with the resistance rapidly increasing and switching on when the maximum temperature has been reached. The device can then be used as an over-temperature protection device to ensure the safety and reliability of electronic components.

Conclusion

The PTFT0805L0030JW is a type of PTC thermistor which is suitable for use in a wide range of applications, particularly those requiring over-temperature protection for sensitive electronic components. The thermistor works on the principle that the resistance changes exponentially with temperature, with the resistance sharply increasing and switching on the device when the maximum temperature has been reached. This provides device protection against over-heating, thus ensuring reliability and safety.
