PolarTEC™ Series PT4-12-F2-3030
Thermoelectric Modules
The PolarTEC™ Series consists of porch-style thermoelectric
modules (TEMs). The hot side of the ceramic has an extended edge
that allows strong lead attachment to accommodate the wiring of
multiple TEMs into an array.
This product line is available in 4, 6, and 8 Amp configurations and is
ideal for high-volume production. Assembled with Bismuth
Telluride semiconductor material and thermally conductive
Aluminum Oxide ceramics, the PolarTEC Series is designed for
higher current and larger heat-pumping applications.
