• Qc Op - displays the cooling performance of the thermoelectric module at the temperature difference requested. The cooling performance shown is at a typical operating point (Iop) set at 75% of the maximum current (Imax). By clicking on the part number, cooling performance (Qc) can be viewed graphically over the entire operating range from minimum to maximum voltage or current (Imin to Imax or Vmin to Vmax).
• V Op - displays the voltage corresponding to the operating current set at 75% Imax.
• Qc Max - displays the maximum cooling performance capability of the thermoelectric module. This value is measured at zero temperature difference with the current set to the maximum effective value. Actual thermoelectric performance is always less than QcMax because of input and output thermal resistances operating through a temperature difference, and the likelihood of operating at more efficient (lower) currents (see Qc Op).
• ΔT Max - displays the maximum difference in temperature seen across the thermoelectric couple. This value is measured at zero heat flow (Qc) with the current set to the maximum effective value. Typically the thermoelectric module is operated at ΔT's much less than ΔT Max in order to move heat from the cold to warm side of the thermoelectric module.

PART NUMBER - displays an active data sheet. You can fine-tune your application requirements by adjusting values for voltage, current, control temp, ambient temp, ΔT, Hot Side thermal resistance or Cold Side thermal resistance and then click the UPDATE button.
