NTC thermistors, or Negative Temperature Coefficient thermistors, are devices used in temperature sensing applications. They are built with a resistance that changes dramatically when exposed to changes in temperature. This property makes them ideal sensors for temperature measurement and control. NHQM221B310T10 is a NTC thermistor from manufacturer Nichido. It has a temperature range of -50°C to +110°C and a standard tolerance of ±10%.

This NTC thermistor is constructed with a lead-free glass-encapsulated package, which is resistant to shocks, corrosion and extreme environmental conditions. The device can be incorporated into a custom circuit design, allowing for added features such as temperature compensation for accuracy. The integrated circuit can measure temperature within a fraction of a degree Celsius making it ideal for temperature control applications.

The working principle on an NTC thermistor relies on the semiconductor material used within the device. The two semiconductor materials used are: n-type and p-type. The n-type material has more free electrons than holes (negative carriers) and the p-type material has more holes than electrons (positive carriers). As the temperature around the thermistor increases, the difference between these semiconductor materials increases, creating a higher electric resistance, resulting in lower current flow through the device.

NTC thermistors are increasingly being used for a range of temperature sensing applications, from consumer electronics with temperature control features to more industrial usage in medical laboratories and health diagnostics. The NHQM221B310T10 model from Nichido is a great device for temperature measurement and control, due to its low temperature range and tolerance. The integrated circuit can allow for further features to be added, such as temperature compensation for improved accuracy.
