R25ºC=10KΩ±2% B25/85=3977K±1.5% NTC Temperature Sensor
The given description refers to an NTC (Negative Temperature Coefficient) temperature sensor with specific parameters:
R25ºC = 10KΩ ± 2%: This indicates the resistance of the sensor at 25 degrees Celsius (ºC). The nominal resistance of the sensor at 25ºC is 10,000 ohms (10KΩ). The ±2% tolerance means that the actual resistance at 25ºC can vary within a range of ±2% around the nominal value, so it can be between 9,800 ohms and 10,200 ohms.
B25/85 = 3977K ± 1.5%: The B25/85 value is the Beta value of the NTC thermistor. It is a constant used in the Steinhart-Hart equation to describe the sensor's temperature-resistance characteristics. The Beta value is typically measured between two temperature points, 25ºC (B25) and 85ºC (B85) in this case. The given value of 3977K indicates the nominal Beta value of the sensor, and the ±1.5% tolerance means that the actual Beta value can vary within a range of ±1.5% around the nominal value.
In summary, the NTC temperature sensor has a resistance of approximately 10KΩ at 25ºC, and its resistance will vary with temperature according to the NTC characteristic curve described by the Beta value of 3977K. The specified tolerances indicate the allowable variations in the sensor's resistance and Beta value, respectively.
