10°C (50°F)

3.00 to 3.73 k?

15°C (59°F)

2.45 to 2.88 k?

20°C (68°F)

1.95 to 2.30 k?

25°C (77°F)

1.60 to 1.80 k?

30°C (86°F)

1.28 to 1.47 k?

35°C (95°F)

1.00 to 1.22 k?

40°C (104°F)

0.80 to 1.00 k?

45°C (113°F)

0.65 to 0.85 k?

50°C (122°F)

0.50 to 0.70 k?

55°C (131°F)

0.44 to 0.60 k?

60°C (140°F)

0.36 to 0.50 k?

NOTICE:

  • Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.
  • When measuring, the sensor temperature must be the same as the ambient temperature.

HINT:

As the temperature increases, the resistance decreases (see the graph).

If the result is not as specified, replace the thermistor assembly.
