RL2004-4429-122-D1

Temperature Sensors - NTC Thermistors

NTC thermistors are very popular temperature sensors because of their low cost, high accuracy, small size, and wide temperature ranges. The RL2004-4429-122-D1 specifically is a negative temperature coefficient thermistor. This means that as the outside temperature increases, the internal resistance of the device decreases.

Application Field

The RL2004-4429-122-D1 thermistor is ideally suited for use in industrial, automotive, and household applications. The thermistor\'s operating range spans from -50°C to 150°C, with a nominal resistance of 44.000k at 25°C. This thermistor is available in a small package of only 3.6mm x 4.7mm. Its size and low cost make it ideal for use in compact designs with tight temperature control.

Working Principle

This device follows the same working principle as all other thermistors: As the temperature rises, the resistance decreases. The RL2004-4429-122-D1 thermistor is unique in that it uses a thermoderived negative temperature coefficient (NTC), meaning that its electrical resistance will decrease as its temperature rises. This principle is based on the fact that, as temperature rises, electrons will move more freely through the crystalline structure of the device. This increased movement of electrons causes the electrical resistance of the device to decrease.

Limitations

While the RL2004-4429-122-D1 is well suited to many applications, the thermistor also has some instances where its use is limited. It cannot be used in temperatures beyond its stated operating temperature range of -50°C and 150°C. This device is especially sensitive to over-temperature conditions, and is not well suited for applications that may experience sudden or extreme temperature fluctuations. Additionally, the device should not be used in applications where precision or extremely accurate readings are required.

Conclusion

The RL2004-4429-122-D1 thermistor is a small, low-cost negative temperature coefficient (NTC) thermistor that is well suited to many industrial, automotive, and household applications. Its operating range spans from -50°C to 150°C, and its small package size makes it ideal for use in compact designs. While the device is suitable for many applications, its usage should be limited to areas where its temperature range is within the stated operating parameters and where extreme temperature accuracy is not necessary.
