Introduction – NTC Thermistors for Temperature Sensors
NTC Thermistors (Negative Temperature Coefficient Thermistors) are semi-conductor-based temperature sensors used to measure temperature in many industrial processes. Thermistors are used in many applications from automotive engines to telecommunications, refrigeration, and commercial baking processes.
B57971S0202J000 – Overview
The B57971S0202J000 is a NTC thermistor developed by EPCOS/TDK. It has a resistance value of 2.2k at 25°C, a temperature coefficient of -3.87 %/K and a power rating of 0.2 W. It has a small outline package (SOP) and is designed to operate in ambient temperatures ranging from -40°C--125°C.
Application Field
The B57971S0202J000 NTC thermistor is suitable for a wide range of applications requiring accurate and reliable temperature sensing. The SOP package makes it well-suited for use in space-constrained areas such as automotive engines and telecommunications systems. The thermistor is also suitable for use in a variety of other applications including:
- Commercial baking and refrigeration
- Home appliances
- Computers and electronics
- Commercial heating systems
- Industrial equipment
Working Principle
NTC thermistors function on the principle of changing resistance with changing temperature. They are made of a semiconductor material that exhibits a decreasing resistance with increasing temperature. The resistance of the thermistor decreases as temperature increases, until a certain point when the resistance becomes practically constant. At this point, the thermistor is said to have reached its “Curie point”. After this point, the thermistor’s resistance increases with increasing temperature.
The B57971S0202J000 thermistor has a temperature coefficient of -3.87 %/K. This means that for every degree Celcius increase in temperature, the resistance of the thermistor will decrease by 3.87%. The thermistor’s resistance at 25°C is 2.2kΩ. This means that at 35°C, the thermistor’s resistance should be equal to 2.07kΩ.
Conclusion – The B57971S0202J000 NTC Thermistor
The B57971S0202J000 NTC thermistor from EPCOS/TDK is a versatile temperature sensor that can be used for a variety of applications from automotive engines to commercial baking processes. The thermistor operates on the principle of changing resistance with changing temperature. It is designed to operate in temperatures ranging from -40°C--125°C, and has a temperature coefficient of -3.87 %/K. The B57971S0202J000 thermistor is an ideal choice for precise and reliable temperature sensing.
