Temperature Sensors - NTC Thermistors have become the go-to choice for many temperature sensing applications due to their relatively small size, accuracy, and wide temperature range. The NHQMM473B400T5 is a common model used for such applications, and is often chosen due to its robust construction and compatibility with both AC and DC power sources.

The NHQMM473B400T5 is a thermistor, which is a type of resistor with a unique temperature-dependent resistance value. As the temperature of the device rises or falls, the resistance of the device changes accordingly. These changes in resistance can be used to measure changes in temperature. This thermistor is a negative temperature co-efficient (NTC) type, meaning that the resistance falls as temperature rises.

The NHQMM473B400T5 has a room temperature resistance of 473 ohms, a dissipation factor of 0.4 watts, and an accuracy of ± 0.25°C across its range. It can measure temperatures between -40 and 150°C, and is capable of doing so accurately to a degree. It is also highly stable in its readings, making it ideal over similar models.

Typically, the NHQMM473B400T5 thermistor is used in applications such as safety measures, temperature monitoring, temperature control, and as part of medical instruments. It is extremely reliable and can be used in systems ranging from industrial through to light commercial and domestic applications.

The thermistor itself is often mounted onto a much smaller printed circuit board and then encased within a plastic or metal housing, protecting it from environmental damage. This allows the thermistor to monitor external temperatures or even be directly exposed to the environment for more accurate readings.

The NHQMM473B400T5 is connected to the power source (AC or DC) and to the sensing circuit. The sensing circuit will then read the voltage changes across the thermistor, convert this to a temperature value, and then be used to display the temperature or trigger alarms/notifications when pre-set thresholds are reached (typically based on pre-determined readings). This setup is commonly referred to as a Voltage Divider circuit, as the thermistor forms part of a voltage divider when being used.

It is this type of setup that allows for the NHQMM473B400T5 thermistor to be used across a diversity of applications, from industry through to medical instruments. Not to mention that its relatively small size and highly stable readings also helps it to find favour for many temperature sensing applications.
