Thermoelectric Technical Reference — Averaged Module Material Parameters at Various Temperatures

For all tables:

SM = Module Seebeck coefficient in volts/K (or volts/degreeC)
RM = Module resistance in ohms
KM = Module thermal conductable in watts/K (or watts/degreeC)

NOTE: The data on the following tables reflects effective module parameters of Ferrotec manufactured TEs, in normal ambient air using thermal grease at both the hot and cold module interfaces. Raw Bismuth Telluride semiconductor material not in module form has substantially different values for these parameters. We do not recommend using this data for the analysis of other manufacturer's modules.
