Thermistors are temperature sensitive resistors, and they are commonly used as thermal sensors in a wide range of applications. The PRF18BF471QS5RB is a PTC (Positive Temperature Coefficient) thermistor. It is a type of resistor whose resistance increases with a rise in temperature.

Application Field of the PRF18BF471QS5RB

The PRF18BF471QS5RB is a type of temperature sensitive resistor available in both axial and radial packages. This specific PTC thermistor is mainly used for the thermal protection of all kinds of electric and electronic equipment, including transformers, motors, and other power equipment. It is also used as a temperature-overload protector in distribution boxes, and its special ultrathin design makes it ideal for the limited space equipment.

This specific thermistor is commonly used as a surge absorber in telecommunications, networks, automotive, consumer electronics, computers, and medical equipment. It is also frequently used in temperature control, temperature compensation, thermal cut-off, and temperature measurement applications.

Working Principle of the PRF18BF471QS5RB

PTC thermistors utilize large molecules composed of polymers, called "doped conductive semiconductors". These molecules can act as semiconductors, and when heated, they tend to change to an insulator. This is the principle behind the PTC thermistor.

The PRF18BF471QS5RB has a temperature coefficient of resistance (TCR) value from -5ppm to +15ppm. The way it works is that when the temperature rises, the resistance of the thermistor increases. As soon as the device reaches its specified temperature set point, the power is shut off and the temperature remains stable. This makes it ideal for the applications mentioned above where thermal protection is required.

The PRF18BF471QS5RB also has a wide tolerances over its specified operating temperatures, meaning that it can withstand wide variations in temperature without any problems. This makes it a reliable and accurate temperature monitoring device.

Conclusion

The PRF18BF471QS5RB is a PTC thermistor that is used as a thermal protector in a wide range of electronic and electrical equipment. It has a temperature coefficient of resistance (TCR) value from -5ppm to +15ppm, making it ideal for temperature control, temperature compensation, thermal cut-off, and temperature measurement applications. It is reliable and accurate, and its ultrathin design makes it perfect for limited space equipment.
