Temperature sensors are one of the most important and often used components in modern electronic systems. The NHQMM103B375T10 (NHQMM) is an especially popular model of NTC thermistor that is widely used for a number of different purposes across different industries. This article will discuss the specific application field and working principle of this device.

Introduction

The NHQMM is a type of NTC thermistor (Negative Temperature Coefficient thermistor), which is a temperature sensing device that employs an electrically conductive material whose resistance is influenced by changes in temperature. An NTC thermistor is typically considered a low cost, reliable and accurate temperature sensing solution. The NHQMM is a specifically designed part, offering desirable features such as high accuracy, compact size and a wide operating temperature range.

Application Field

The NHQMM offers many advantages over other temperature sensing solutions, which makes it suitable for a variety of applications. The device is often used in thermal management applications, such as in industrial and automotive systems, for accurately controlling fan and air conditioning systems. It is also widely employed in medical equipment, providing precise temperature control in patient monitoring systems. Additionally, the NHQMM is a popular choice for temperature sensing in smart home systems, Consumer Electronics (CE) products and home appliances.

Working Principle

The NHQMM works by utilising the resistance-temperature response of an alloy in which the resistance of the device changes in a predictable manner with changes in temperature. It is a type of NTC thermistor which means it exhibits an electrical resistance which decreases when the temperature increases. The device switching point is typically taken as the temperature at which the resistance falls to 25% the value measured at the lowest temperature.

The resistance of the NHQMM is measured by connecting the device to an external power source and measuring the voltage drop across the device. This voltage drop is then used to calculate the resistance of the device using Ohm’s law. By comparing the resistance at different temperatures, the device’s temperature response can be measured and monitored more accurately.

Conclusion

The NHQMM103B375T10 NTC thermistor is a reliable and accurate temperature sensor that is suitable for many different applications. The device has a wide operating temperature range, high accuracy and a compact size, making it a popular choice for temperature sensing solutions. Additionally, the NHQMM works by utilising the resistance-temperature response of an alloy in which the resistance of the device changes in a predictable manner with changes in temperature.
