Thermistors are a type of resistance-based temperature sensor that provides a reliable and highly sensitive solution for measuring temperature. The RL3004-10.8K-138-D1 is a Negative Temperature Coefficient (NTC) thermistor made of a high-temperature ceramic material and housed in a 5mm × 5mm × 6mm epoxy package. It is designed for small-scale temperature detections such as those found in computers and other electronic equipment.

Unlike Positive Temperature Coefficient (PTC) thermistors, NTC thermistors offer a negative change in resistance with an increase in temperature. The RL3004-10.8K-138-D1 has a resistance of 10.8K Ω at 25°C and will decrease its resistance as the temperature increases. This decrease in resistance is useful for measuring small decreases in temperature over time.

One of the main applications for the RL3004-10.8K-138-D1 is as an over-temperature protection device for computers and other electronic equipment. As temperatures increase, the resistance of the NTC thermistor decreases, allowing a larger amount of current to pass through the device. This, in turn, triggers the temperature sensor and can shut the device down in the event of an excessive temperature increase.

The RL3004-10.8K-138-D1 has an operating temperature range of -50°C to 125°C and can detect small changes in temperature with an accuracy of +/-0.25°C. This makes it ideal for use in a range of temperature measurements, from medical instruments and automotive combustion to data centers and industrial equipment.

The RL3004-10.8K-138-D1 has a very simple working principle. The negative temperature coefficient of the device causes its resistance to decrease with an increase in temperature. This change in resistance is detected by the device’s internal circuitry, allowing it to accurately measure and monitor temperature changes.

The RL3004-10.8K-138-D1 is a reliable and cost-effective solution for temperature sensing applications. Its small size and wide operating range make it perfect for applications where precise temperature measurements and over-temperature protection are needed. It is a great choice for designers looking for an accurate and reliable NTC thermistor for their temperature measurement needs.
