Temperature dependent resistor. Used as temperature sensor with high precision, e.g. combined with an Arduino.
To be used with a 0.1 % resistor (item number 603227) in a voltage divider.
Temperature range: 40°C to 125°C. Nominal resistance value at 25°C: 1000000 Ω.
Other resistance values: Download table on the Documents tap. The measured temperature deviates maximum 0.1°C from the table values in the temperature interval 0°C to 70°C.
The table is very closely approximated by the Steinhart-Hart equation which can be seen in one of the images above. The equation can also be found in a document on the Documents tap. The deviation between the equation and the tabulated values is maximum 0.010°C in the 0°C to 70°C range, and maximum 0.025°C in the complete -40°C to 125°C range.
Time constant in liquid: < 1 s
Thermal resistance in still air: 1.33 K/mW
Lead diameter: 0.20 mm
Specific thermal conductivity of the leads: 3.5 W/(m∙K)
(Which is more than 100 times lower than for Cu.)
