Temperature Sensors - NTC Thermistors are widely used in many industries for temperature measurement and control. In this article, we will discuss the application field and working principle of NHQT104B425T5 which is a type of NTC thermistor.

An NTC thermistor is typically composed of a sintered semiconductor material made of metal oxides in a ceramic body. The temperature-dependency of the NTC thermistors is based on the fact that the resistance decreases as the temperature increases. NHQT104B425T5 is a negative temperature coefficient (NTC-100K) thermistor with a resistant tolerance of 10%. It has a 25C B-value of 3950 (K).The B-value is the temperature coefficient which is used to convert the resistance to temperature.

The typical application field of NHQT104B425T5 is in the fields such as temperature sensors for HVAC systems, automotive and industrial equipment where the precise measurement of the temperature is required. It can also be used for temperature compensation in electronic circuits. The temperature range for this thermistor is -40℃ to +105℃.

The working principle of the NHQT104B425T5 is based on Seebeck effect which states that when two different metals are connected together at two different points and heated, an emf will be induced in the circuit. The emf of this thermistor is a function of the temperature difference between the two points and can be used to measure the temperature. The thermistor is connected to the two probes and the temperature is calculated by measuring the voltage across the thermistor. The resistance of the thermistor is then calculated by dividing the voltage by the current.

NHQT104B425T5 is built with a high precision material and has a good thermal stability. It requires less accuracy and offers very fast response time. The low thermal time constant ensures that the thermistor can detect even smaller changes in temperature. Furthermore, the low power consumption also makes it a cost effective solution for temperature detection.

Overall, NHQT104B425T5 is a very reliable temperature measurement device which is used in many industries for precise temperature measurement and control. It has a wide operating temperature range and provides excellent thermal stability, fast response time and low power consumption. Therefore, it is suitable for various temperature sensing applications.
