Resistance Tolerances
Standard tolerance is ±50% (tolerance code letter R at
end of code number). For other tolerances, substitute
letter from Table B for suffix R at end of code number.
The CTFP07DE105R is 1 MΩ ±50% when measured in
liquid nitrogen. Refer to the table D for resistance ratio vs
temperature characteristics.

Cryogenic Probes
These cryogenic thermistors are extremely useful for liquid level detection in
various cryogenic liquids. In this application, the thermistor is slightly self-heated
by passing a small current through the unit. The heat generated in the unit is
more easily dissipated when the thermistor is immersed in cryogenic fluid than
when the fluid level falls below the thermistor. The resulting change in thermistor
temperature is easily detected by the change in resistance.
