Temperature Sensors – PTC Thermistors PTC thermistors are thermistors that have a positive temperature coefficient, meaning that their resistance increases with increasing temperature. PRF18AS471QS5RB is a type of PTC thermistor designed for temperature-sensing applications. It is a surface-mount device and offers a NTC resistance of 18KOhm at 25°C. It has a wide range of operating temperature, from -40°C to +170°C, and is capable of withstanding large voltage spikes.The PRF18AS471QS5RB is a thermistor that can be used for a wide range of applications. It is an ideal temperature sensor for residential applications, where it can be used to monitor the internal temperature of a refrigerator or AC unit. It can also be used in automotive applications, where it can be used to monitor the temperature of engine coolant or transmission fluid. In addition, it can be used in industrial applications, where it can be used to measure the temperature of machines, liquids, and even air.In terms of working principle, the PRF18AS471QS5RB relies on an electrical circuit based on the basic ohm\'s law. The device has two terminals: one is connected to a power supply, and one is connected to ground. When the temperature of the environment changes, the resistance of the PRF18AS471QS5RB changes, and this change in resistance is detected by the circuit. The change in resistance is then converted into a voltage signal, which is read by the circuit and converted into a temperature reading.In terms of advantages, the PRF18AS471QS5RB offers a wide range of operating temperatures, high reliability, and excellent accuracy. Furthermore, the device is not affected by electrical noise and can be used in environments with high levels of electromagnetic interference. In addition, since it is a surface-mount device, it is easy to install and requires minimal wiring.The PRF18AS471QS5RB is a versatile and robust thermistor that can be used in a wide range of temperature sensing applications. It is capable of withstanding large voltage spikes, is highly reliable and accurate, and offers a wide range of operating temperatures. Furthermore, it is easy to install and requires minimal wiring.
