NTC thermistors (Negative Temperature Coefficient thermistors) are thermally sensitive semiconductor devices that act as resistors when exposed to increasing temperatures. The NHQ474B435T5 is a popular NTC thermistor used in temperature control applications. This article will discuss the application fields and working principles of the NHQ474B435T5.

The NHQ474B435T5 is capable of accurately measuring temperature in a wide range of applications. It is well-suited for automotive applications due to its ability to operate over a large temperature range without introducing errors. It can also be used in various refrigeration and air conditioning applications where temperature control is necessary. Industrial applications such as medical equipment, energy efficiency systems, and cooling systems can also benefit from the NHQ474B435T5.

NTC thermistors are made of a semiconductor material with major elements such as nickel, cobalt or manganese. The structure of the NHQ474B435T5 consists of a platinum-doped silicon wafer with a thin film of NTC material. The semiconductor material in NTC thermistors changes its electrical resistance with increasing temperatures. As the temperature of the thermistor rises, the electrical resistance of the NHQ474B435T5 also increases.

NTC thermistors are usually connected in a Wheatstone Bridge circuit as part of a temperature control system. The Wheatstone Bridge is composed of four resistors connected in a square with a gap between them. The gap is filled with the NTC thermistor. When the circuit is energized, an alternating current flows through the Wheatstone bridge and the voltage difference between the terminals at the ends of the bridge is measured. This voltage difference is directly proportional to the temperature of the NHQ474B435T5.

The NHQ474B435T5 has a wide range of uses, including automotive, refrigeration and air conditioning, industrial and medical applications. It is capable of accurately measuring temperature over a wide range and can be used in temperature control systems to ensure accuracy and efficiency. The NHQ474B435T5 is connected to a Wheatstone Bridge circuit and is able to detect the difference in voltage at the two ends of the bridge. This voltage difference is directly proportional to the temperature of the NHQ474B435T5.
