Electrical and Thermal Performance

For maximum performance, be sure to orient the CONTROL side of the TEC against the application to be managed and the AMBIENT side against the heat sink or other heat rejection method. The CONTROL side is always opposite the side with lead attachments. Lead attachment is a passive heat loss and less impactful if located on the side that attaches to the heat exchanger.

Use the sliders, input fields and [UPDATE] button below to enter your application's electrical and thermal conditions. Use the Graph Y and X Axis buttons to display a variety of performance curves and use the Voltage/Current slider to choose the electrical operating point to display performance.
