NTC Thermistors, or Negative Temperature Coefficient Thermistors are temperature sensors that are widely used in industrial and consumer electronic applications. They are a form of thermistor, which is a semiconductor device that changes its resistance according to changes in temperature. The ACC004 is a NTC Thermistor specifically designed for applications that require accurate temperature measurements over a wide range of temperature ranges.

The ACC004 is a precision NTC thermistor with an accuracy of 0.25°C over a temperature range of -40°C to +60°C. It is small and lightweight, making it easy to use in applications such as closed-loop temperature measurement systems, HVAC systems, and automotive applications. The ACC004 is also designed to be robust, allowing it to withstand extreme temperature conditions. It is resistant to shock and vibration, and can be used in high-temperature and corrosion-resistant applications.

The ACC004 works by taking advantage of the temperature-sensitive nature of thermistors. When exposed to a temperature change, the thermistor requires time to establish a new equilibrium. This phenomenon of resistance acclimatization is known as Self-Heating. The resistance of the thermistor changes linearly when the application\'s temperature changes. This ensures that the resistance maintains a consistent value in the face of changes in temperature.

To ensure that the ACC004 accurately measures the temperature, the thermistor\'s self-heating resistance must be measured. The resistance can be measured by applying a voltage across the thermistor in a given temperature range, and then measuring the voltage drop. The voltage applied must be adjusted to achieve an accurate temperature reading. The measured resistance can then be used to calculate the temperature.

The ACC004 is designed for easy integration into existing applications. It is available in a wide range of package sizes, from tiny TO-39 versions to larger axial leaded styles. The thermistor can be mounted using adhesive or suitable thermal grease, or permanently attached with soldering or welding techniques. The thermistor can be connected to a solution that is electrically conductive, to an external temperature control unit or to a microcontroller such as an Arduino board.

The ACC004 is a precision NTC thermistor that is designed for accurate temperature measurements over a wide temperature range. Its resistance changes linearly in relation to temperature and is measured by applying a voltage across the thermistor and then measuring the voltage drop. The thermistor is robust and can be easily integrated into existing electronics applications due to its varied package sizes.
