NTC thermistors, short for negative temperature coefficient thermistors, are electronic components used in temperature measurement, based on the NTC thermistor concept which states that the resistance of the thermistor decreases as the temperature increases, enabling temperature measurement and compensation.

The RL2012-5506-120-D1 is a small, economical NTC thermistor designed for temperature sensing and related applications. It provides fast response time and excellent temperature accuracy due to its low thermal resistance. With a wide temperature range of -60°C to +170°C (-76°F to +338°F), the RL2012-5506-120-D1 is able to measure temperatures in environments ranging from extremely cold to extremely hot.

Its built-in resistance is factory-calibrated, reducing the need for additional adjustable hardware. The device also features a built-in resistance tolerance of ±1.4%, allowing it to provide accuracy without having to be adjusted. It also has a small form factor, which allows it to be used in a wide variety of applications, including automotive, telecom infrastructure, testing and measuring instruments, power supply systems, and other temperature measurement and sensing applications.

In terms of its working principle, the principle of NTC thermistors is based on the fact that if a current is passed through a resistor, heat is generated. This property of a resistor is known as ohmic heating. If two NTC thermistors are placed in series, external temperature affects the two resistors disproportionately. As one of the resistors gets colder, its resistance decreases, while the other one increases. This allows the device to measure the temperature difference. By measuring the degree of resistance change, it can then measure the temperature of the environment.

The RL2012-5506-120-D1 is designed to provide fast response time and excellent temperature accuracy. It is economical, small, and has a wide temperature range, making it the perfect choice for temperature sensing and related applications. It is ideal for use in automotive, telecom infrastructure, testing and measuring instruments, power supply systems and other temperature measurement and sensing applications.
