Electrical Characteristics

Minimum and maximum values specified over operating case temperature range and end of life (EOL), and typical

values are for 25

°C and beginning of life (BOL), unless otherwise specified

* The resistance of the thermistor is inversely proportional to the temperature. The temperature can be calculated from the resistance value

using the Steinhart-Hart equation: 1/T = A + B ln(R) + C ln(R)

C = 4.5421 x 10
