NTC Thermistors are widely used in temperature sensing applications due to their sensitive response to temperature and ease of use. The 120-103FAJ-Q01 is designed for use in a wide range of applications ranging from automotive to medical. In this article we will discuss the application field and working principle of the 120-103FAJ-Q01.

The 120-103FAJ-Q01 is a Negative Temperature Coefficient (NTC) Thermistor that is designed to act as a sensor to measure temperatures from -40°C up to +125°C with a high degree of accuracy. The 120-103FAJ-Q01 is a highly reliable temperature sensor with a very low temperature coefficient of resistance (TCR), making it well-suited for temperature measurements in a variety of applications. The 120-103FAJ-Q01 is particularly well-suited for automotive applications, such as engine cooling systems and exhaust gas systems. Additionally, the thermistor is often used in medical applications, such as in incubators or blood glucose meters. Lastly, the 120-103FAJ-Q01 is used in industrial process control applications, as well as in air conditioning and HVAC.

The working principle of the 120-103FAJ-Q01 is based on the behavior of a metal oxide resistor, also known as a metal-oxide film resistive element (MOFRE). When a current is passed through a MOFRE, its resistance will change with the temperature. The 120-103FAJ-Q01 is designed to measure and detect this change in resistance, and convert it into a temperature measurement. A combination of the sensor’s construction and doping ratio results in a negative temperature coefficient of resistance, allowing for an accurate measurement of temperatures in its specified range.

The 120-103FAJ-Q01 utilizes a small, non-invasive design, which can be placed in any location with minimal space requirements. With a small-sized ceramic-encased design and three lead-free wires, the thermistor can be remotely deployed for easy access and temperature measurements. Moreover, its construction facilitates the improved heat transfer from its environment, providing an even more accurate measurement. The 120-103FAJ-Q01 can also be used with a variety of power sources, including AC and DC Voltage as well as an AC and DC current.

The 120-103FAJ-Q01 is a reliable and precise temperature sensor that is designed for use in a broad range of applications. Its small size, remote deployable design, and wide temperature range make it well-suited for applications ranging from automotive to medical. The thermistor works on the principle of a metal-oxide film resistive element, and its negative temperature coefficient of resistance allows for accurate temperature readings in its specified range. The 120-103FAJ-Q01 is an ideal choice for reliable and accurate temperature sensing in a variety of applications.
