1)
Due to the nonlinear conversion from
Ω
to °C the stability in °C depends on the operating conditions
and the characteristics of the thermistor. E.g. for a typical thermistor at a set point of 10k
Ω
(25°C), a
0.5
Ω
stability translates into about 1mK temperature stability. At a set point of 5k
Ω
(38°C), the stability
is about 2mK.
