PTC thermistors are temperature sensing elements that use a predictable and repeatable resistance-temperature relationship to measure and control temperatures in a variety of applications. The PRF18AR471QB5RB is one such PTC thermistor, and it has a variety of features that make it useful for various applications. It can help provide temperature stability in a variety of environments, and its resistance-temperature relationship makes it suited to a variety of temperature measurement and control applications.

A PTC thermistor is basically a metal oxide semiconductor that has a positive temperature coefficient (PTC). The resistance of the PTC thermistor increases with an increase in temperature. The PRF18AR471QB5RB is a heavy-duty resistor element with a 1.125 inch diameter. Its resistance at 25°C is 471 ohms, and its insulation resistance is greater than 10 megohms at 500VDC. The power rating for the PRF18AR471QB5RB is 0.125W (125mW) at 70°C.

The PRF18AR471QB5RB is typically used in general-temperature measurement applications where its resistance-temperature relationship is useful. It is also useful in temperature control, data loggers and temperature stabilizing systems. The resistance-temperature characteristics of the PRF18AR471QB5RB provide superior performance in these applications.

The working principle of the PRF18AR471QB5RB is straightforward. As the temperature increases, the resistance of the thermistor increases. This resistance change is then measured using an adjustable resistive divider network, and the temperature can be calculated based on the resistance. The adjustable resistive divider network is typically made up of two resistors, one of which is adjustable to compensate for the temperature coefficient of the thermistor.

The PRF18AR471QB5RB is an excellent choice for use in general temperature sensing and control applications. Its size and resistance-temperature relationship make it ideal for use in a variety of temperature-dependent systems.
