Temperature Sensors - NTC Thermistors are a type of thermistor that have a negative temperature coefficient (NTC), meaning its resistance decreases as the temperature increases. They consist of a metal oxide semiconductor formed into a bead, disc, or chip shape, whose resistance is proportional to the temperature. NTC Thermistors offer fast response times, good accuracy, low power consumption, small size, and durability.

NHQ104B425T5 is a NTC Thermistor designed for high-temperature and high-voltage applications. It has a resistance of 4.2KΩ at 25℃, and its temperature range is from -40 - 250℃. The resistance of NHQ104B425T5 varies drastically with temperature, decreasing by a factor of 10 when the temperature is increased by 10K. It is rated for a maximum voltage of 25V, and its power rating is 1/4 W. It has a tolerance of ±20%.

NHQ104B425T5 has a wide range of applications, including temperature sensing in electronic appliances, automotive and medical equipment, as well as industrial manufacturing. It is ideal for applications where a high degree of accuracy in temperature sensing is required. It can be used in devices such as ovens, microwaves, and refrigerators to measure and control the temperature.

The working principle of NTC Thermistor is based on semiconductor thermoelectrics. It follows the Law of Stein-Hall which states that the temperature of a semiconductor is inversely proportional to the electrical resistance in the semiconductor. When a current passes through an NTC Thermistor, it creates a temperature drop in the thermistor, changing its resistance. This resistance can be measured and used to calculate the temperature.

NHQ104B425T5 is a great option for temperature sensing applications that require high accuracy. Its quick response times, wide temperature range, and high voltage rating make it a great choice for high-precision temperature sensing.
