Temperature Sensors NTC Thermistors

B57561G0502H000 Application Field and Working Principle

NTC thermistors are temperature sensors that accurately measure and control temperature due to their predictable resistance–temperature relationship. B57561G0502H000 thermistor from EPCOS is a negative temperature coefficient thermistor (NTC thermistor) with the resistance decreasing with increasing temperature. This device has a wide temperature range due to size-to-resistance ratio and different mountings, making it suitable for a range of applications. Its resistance value at 25°C is 5.2Ω and its tolerance is ±10%.

The application field of B57561G0502H000 thermistor is vast. Its features, such as wide temperature range, make it suitable for automotive applications, HVAC, and industrial processes. It is used to measure temperature in automotive engine control systems, HVAC systems, and medical equipment. Its compact shape makes it perfect for use in various electronic systems for controlling the voltage, current and power. This thermistor can also be used for electronic speed control in domestic appliances and monitoring of motor temperature in power tools.

As this thermistor has a predictable resistance–temperature relationship, it works on the principle of the negative temperature coefficient of resistance. It follows the rule that as the temperature increases, its resistance decreases. Its resistance decreases exponentially with increasing temperature, so at high temperatures, its resistance changes dramatically. The rate of change is proportional to the temperature and the size of the thermistor. The B57561G0502H000 thermistor is made of a semiconducting material which has non-linear electrical resistance.

In summary, B57561G0502H000 thermistor from EPCOS demonstrates excellent performance due to its predictable resistance–temperature relationship. It operates on a negative temperature coefficient of resistance principle, which results in a wide temperature range. This device has an impressive resistance value of 5.2Ω at 25°C, with a tolerance of ±10%. Owing to its compact shape and predictable resistance–temperature relationship, it is suitable for various applications like automotive, HVAC, and industrial processes.
