CMFB3550103FNT

Temperature Sensors - NTC Thermistors

NTC (negative temperature coefficient) thermistors are thermally sensitive resistors used for temperature detection and management in a variety of commercial and industrial processes. The CMFB3550103FNT thermistor is a particularly versatile type that can be used in applications exceeding 300°C and effectively manage temperature measurements and thermal modelling tasks.

Application Field

The CMFB3550103FNT thermistor is designed for use in extreme operating temperatures, from 300°C to 500°C. It is suitable for use in thermal engineering, automotive, medical, aerospace and industrial process control applications. As a temperature-sensing resistive device, it is also used in temperature measurement for goods in process, industrial exhausts, and energy recovery systems.

Working Principle

NTC thermistors measure temperature by utilizing their temperature coefficient curve. The CMFB3550103FNT thermistor exhibits the characteristic low-resistance values at high temperatures and high-resistance at low temperatures. At lower temperatures, the resistance increases, and at higher temperature the resistance drops. This phenomenon follows the Arrhenius law, which states that the rate of chemical reaction is proportional to the temperature.

In more technical terms, the CMFB3550103FNT thermistor functions by utilizing its semiconductor junction, which features a PN-junction that can measure relative temperature changes. This enables the thermistor to detect differential thermal events between two points, which gets registered as a change in resistance. The two suitable front-end electronic interfaces are current-mode and voltage-mode, which can be programmed to detect changes in resistance and generate output readings.

The CMFB3550103FNT also has low self-heating characteristics which are beneficial for sensitive temperature measurements. It also features an improved reliability and durability, which helps extend its useful life cycle tenfold. With the CMFB3550103FNT, customers benefit from an easy-to-use interface and an efficient way to capture temperature changes within any application.
