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 10kΩ (25°C), a
0.5Ω stability translates into about 1mK temperature stability. At a set point of 5kΩ (38°C), the stability
is about 2mK.
