For thermistors, there is a color code for the reference resistance (@25C) on the package (if it's Vishay manuf). See the link below.

I've used the 'em before with AVRs; more than ref res type. The only one I still have in the shipping sleeve is the 10K reference, (Digikey # is BC1482) but there's a whole range of resistances to fit your specific ADC. It's pretty darn small, but the code does match the datasheet.

Here's the Vishay datasheet. If it doesn't have the color code, test the resistance at temperature and compare to the data specs.. Maybe it will perform similarly. Sorry, that's all I know.

Well, I don't know any thermoresister at all and I am quite good with electronics...
But if it is unknown it means exactly that: unknown.
Get the part identification, circuit diagram- or schematics with parts list or if still working measure it and compare it to temperature tables of known datasheets.
