Hello.
Resistors have TCR. Ordinary carbon resistor have +-200ppm and more. But now i have looking for resistor, where i do not care about absolute value even in changing temperature, but i have to know how big change of TCR is in time. I want use it in thermostate, for polarisation of NTC. Nomen-oment for NTC resistor drift of TCR are specified.
Did i should use low TCR resistors (metal film) or ordinary carbon film resistor can fit in my ideas?
Sincerely.
Simon
