For a TE cooler tempe-

rature controlling NTC

thermistor is mounted onto

the cold side of a TE

cooler. This thermistor is

applied in a scheme with

serial loading resistor

and a reference (Fig.

3.22).

The typical dependence of thermistor resistance on

temperature is presented in Fig. 3.20. The dark area

around the curve marks technological deviation

determined by resistance and Beta Constant straggling

from rated values.
