Temperature Sensors - NTC Thermistors

NTC thermistors are a type of temperature sensor widely utilized for temperature measurements in electronics and other applications. One such thermistor is the NHQM472B355T10, a negative temperature coefficient (NTC) thermistor with linear voltage output and a resistance of 10 ohms at 25°C.

In general, NTC thermistors are composed of a semiconductor material such as sintered metal oxides or polycrystalline films. They respond to temperature changes by altering their electrical resistance. Their resistance decreases with increasing temperature, as opposed to positive temperature coefficient (PTC) thermistors whose resistance increases with temperature. By measuring the resistance of the thermistor, the temperature can be calculated.

The NHQM472B355T10 thermistor has a range of -40°C to +300°C and a linear voltage output of 0~5V when connected to a five-volt power supply. As a NTC thermistor, its resistance decreases with increasing temperature. Its B value ranges from 3450K to 4000K, with 3550K being typical. It’s made of metal oxide, with an operating life of at least 10,000 cycles.

The NHQM472B355T10 is commonly used for measurements in applications such as: HVAC systems, automotive, medical instrumentation, industrial temperature control, etc. It can be used to measure rapidly changing temperatures in a wide range of temperature sensitive systems. Its linear voltage output makes it easier to be used for digital measurements.

The working principle of the NHQM472B355T10 thermistor is based on the change of electrical resistance with temperature. Its resistance is inversely proportional to the temperature, meaning that as the temperature increases, the resistance of the thermistor decreases. The thermistor’s resistance can be calculated from the equation: R = R25 * e ^ (B * (T-25)), where R25 is the resistance of the thermistor at 25°C, B is the thermistor’s B value and T is the temperature of the thermistor.

The NHQM472B355T10 thermistor is an accurate and reliable temperature measurement device used in a wide range of electronic applications. Its working principle is based on the change of electrical resistance with temperature, making it easy to use and read. This thermistor is also versatile, as it can be used to measure rapidly changing temperatures in various temperature sensitive systems.
