Temperature Sensors - NTC Thermistors

NTC thermistors are a type of temperature sensor. The USP3986-RD is a particular NTC thermistor from Panasonic, which has a temperature range of -40 to 150°C and a resistance range of 100K to 10KΩ. It is an ideal choice for a variety of applications, such as automotive, medical, and consumer electronics.

Applications

NTC thermistors such as the USP3986-RD can be used for a variety of temperature sensing applications. These applications include automobile engine control systems, temperature control for medical devices, and consumer electronics. For example, in cars, NTC thermistors can be used as a temperature sensor in the air filter box, coolant fan motor, exhaust manifold, as well as a variety of other parts of the car.

NTC thermistors can also be used for medical temperature sensing. For example, they can be used to monitor body temperature, or as temperature sensors in medical devices such as dialysis machines. Finally, they can also be used in consumer electronics for temperature sensing. This includes power adaptors, computer motherboards, cordless phones, and many other devices.

Working Principle

NTC thermistors work by taking advantage of the fact that the resistance of an NTC thermistor decreases as temperature increases. This is because of a physical property of the thermistor called the “emissivity” which is basically a measure of how much heat energy is absorbed or released by the component when exposed to temperature changes. As temperature increases, the emissivity of the NTC thermistor decreases causing its resistance to decrease. This is what allows it to be used as a temperature sensor.

The USP3986-RD has a resistance range of 100K to 10KΩ, a temperature range of -40 to 150°C, and a shock resistance of 100G. This means that it is able to accurately measure a wide range of temperatures and is able to withstand high levels of shock and vibration. This makes it ideal for automotive and medical applications.

Conclusion

The USP3986-RD is a type of NTC thermistor from Panasonic, and is an ideal choice for a variety of applications, such as automotive, medical, and consumer electronics. It has a resistance range of 100K to 10KΩ, a temperature range of -40 to 150°C, and a shock resistance of 100G. It works by taking advantage of the fact that the resistance of an NTC thermistor decreases as temperature increases.
