ET Series

The ET Series is a miniature thermoelectric module (TEM) that uses proprietary solder construction that melts at 232°C.  This product series is primarily used in applications to stabilize the temperature of sensitive optical components in telecom and photonics industries. This product line is available in multiple configurations and surface finishing options. Assembled with Bismuth Telluride semiconductor material and thermally conductive Aluminum Oxide ceramics the ET Series is designed for lower current and lower heat-pumping applications. Custom designs are available to accommodate metallization pretinning ceramic patterns and solder posts however MOQ applies.
