RL1003-49.2-59-D1 Temperature Sensors – NTC Thermistors

The RL1003-49.2-59-D1 temperature sensor is one type of NTC thermistor, a device that uses the NTC (negative temperature coefficient) effect to measure temperature. This particular type of thermistor is a surface mounted device used for measuring temperature over a range of -20°C to +50°C.

What is NTC Thermistor?

NTC thermistors are solid state devices that respond to changing temperatures. The NTC effect is a phenomenon in which the electrical resistance of the thermistor device decreases as temperature increases. This effect can be used to measure temperature over a range of temperatures. NTC thermistors are increasingly replacing traditional temperature sensors such as mechanical thermocouples and RTDs (Resistance Temperature Detectors) due to their accuracy, stability, fast response, and low cost.

How Does the RL1003-49.2-59-D1 Work?

The RL1003-49.2-59-D1 works by measuring the resistance of the thermistor device as it changes in response to changes in temperature. This type of thermistor is designed to employ the NTC effect to provide an output in the form of a voltage signal with the resistance changing across the range of -20°C to +50°C correlated to the output voltage signal. The device features a leaded package; suitable for both SMT (Surface Mount Technology) and through hole mounting.The RL1003-49.2-59-D1 has a high accuracy temperature range of -20°C to +50°C, with Resistances of 10Ohm – 57KOhm (10K @ 25°C). It is designed to be used in a variety of applications, such as switched mode power supplies, mobile phones, portable electronics, automotive, industrial controllers, and thermally controlled LED lighting.

What are the Advantages of NTC Thermistors?

NTC thermistors offer a range of advantages over traditional temperature sensors, such as mechanical thermocouples and RTDs. First, they are much cheaper than traditional sensors, and can be produced in much larger quantities, allowing them to be used in larger scale applications. In addition, they are much more accurate and stable than the traditional sensors. They also have a very fast response time, allowing them to be used in applications where very quick changes must be detected. Lastly, NTC thermistors are small and have a very low power consumption, making them ideal for use in small, battery-powered devices.

Conclusion

The RL1003-49.2-59-D1 NTC thermistor is a low-cost, accurate, and stable surface mounted temperature sensor. It is designed for use in a variety of applications, from mobile phones, to switched mode power supplies, to automotive and industrial controllers. It is a small, low-power device featuring a high accuracy temperature range of -20°C to +50°C, with Resistances of 10Ohm – 57KOhm (10K @ 25°C). This thermistor offers a range of advantages over traditional temperature sensors, such as mechanical thermocouples and RTDs, including low-cost, fast response time, and small size and low power consumption.
