End of Life


The ThermaTEC™ Series and HOT OptoTEC™ Series of thermoelectric modules (TEMs) have been superceded by the HiTemp ET Series for designs operating at high temperatures. The HiTemp product line is available in more configurations as well as drop-in replacements for applications that operate in temperatures above 80°C or that require both heating and cooling mode (reverse polarity). Assembled with proprietary solder construction, Bismuth Telluride semiconductor material and thermally conductive Aluminum Oxide ceramics, the HiTemp ET Series replaces the ThermaTEC™ Series for higher current and larger heat-pumping applications.
