Temperature Sensors – NTC Thermistors

Temperature sensing is one of the most important measurements in the physical world, and over time,sensitive, reliable, and cost-effective temperature sensors have become increasingly important. The RL1005-108.2K-138-D1 is one such temperature-sensing device, an NTC thermistor.

An NTC thermistor is a type of thermistor in which the resistance of the device decreases significantly with the increase of temperature. In an NTC thermistor, the temperature coefficient of resistance is negative. This makes them ideal for applications that need to measure and monitor temperature changes.

The RL1005-108.2K-138-D1 is a NTC thermistor with a nominal resistance of 108.2K (Ohms) at 25°C and a range of -40 to 125°C. It also has a tolerance of ±20°C and a beta value of 3550K. The RL1005-108.2K-138-D1 is a chip-type thermistor with a 200V rating, making it suitable for a wide range of applications.

The working principle of the RL1005-108.2K-138-D1 is simple yet effective. The NTC thermistor comprises of a metal oxide semiconductor material made of platinum, nickel, and copper. As the temperature changes, the metal core expands and contracts, causing a resistance change in the thermistor. This resistance change is then used to measure the temperature, and the reading is then converted into a signal which can be used by other devices to determine the temperature.

The RL1005-108.2K-138-D1 is suitable for a wide range of applications, including thermal protection, temperature monitoring, temperature compensation and protection, temperature sensing, and over-temperature alarm. It is widely used in consumer electronics, automotive, and home appliances. It can also be used as a heating element in temperature controlled systems, as well as in other industrial and medical applications.

In summary, the RL1005-108.2K-138-D1 is a reliable, cost-effective NTC thermistor with a wide range of applications. The device’s working principle is based on the expansion and contraction of its metal core, which directly affects its resistance and allows it to accurately measure temperature changes.
