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.
FEATURES
• Strong Lead Attachment
• Precise Temperature Control
• Reliable Solid State Operation
• No Sound or Vibration
• DC Operation
• RoHS Compliant
