Temperature Sensors - NTC Thermistors are electronic components, often made of ceramic material, which produce a change in electrical resistance when subjected to changes in temperature. Generally there are two distinguishable kinds of thermistors; the most common are Negative Temperature Coefficients (NTCs) and the less common are Positive Temperature Coefficients (PTCs).

NTC thermistors can be broadly classified as those being used for temperature sensing and those being used for temperature protection. Applications where NTC thermistors are used in temperature sensing involve measuring and controlling the temperature of solid or liquid material, bearing temperature or engine temperature. NTC thermistors are also used in temperature protection, which involves controlling the temperature of electrical components.

The CWF3AA202F3470 is a NTC thermistor intended for use in sensing temperature. This thermistor has a β value of 3470, which is what determines the temperature resolution and sensitivity. The thermals feature of this NTC thermistor is its ability to sense temperature in both hot and cold environments. This ability makes it perfect for sensing temperature over a wide range of temperatures.

The CWF3AA202F3470 thermistor works by changing its electrical resistance in response to changes in temperature. The resistance of the thermistor is proportional to the temperature. However, the resistance of a thermistor decreases as the temperature increases. This decrease in resistance is what makes a thermistor suited to sensing temperature, since resistance decreases over a given temperature range.

When connected to a circuit, the thermistor acts like a variable resistor, meaning that its resistance is adjustable depending on the temperature. The resistance of the thermistor can be measured by applying a voltage across it and measuring the resulting current. The resistance of the thermistor is then calculated from the supply voltage and current. This information can then be used to determine the temperature.

The CWF3AA202F3470 thermistor can be used in a variety of temperature sensing applications. It is ideal for measuring and controlling the temperature of solid or liquid material, bearing temperature or engine temperature. It can also be used as a temperature protection device to prevent electrical components from overheating. This thermistor is also suitable for use in temperature control systems, and can be incorporated into electronic circuits for measuring and controlling temperature.

The CWF3AA202F3470 thermistor is a reliable and accurate temperature sensor. It is easy to integrate into electronic circuits, and its ability to measure temperature over a wide range of temperatures makes it suitable for use in a variety of temperature sensing applications. The thermistor\'s change in resistance in response to a change in temperature also makes it suitable for temperature protection applications, helping to ensure protection for electrical components from temperature extremes.
