OptoTEC Series


The OptoTEC™ Series is a miniature thermoelectric module (TEM). This product series is primarily used in applications to stabilize the temperature of sensitive optical components in the 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 OptoTEC™ 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. Internal solder construction is denoted in prefix of part description: 138°C (OT), 232°C (ET) and 271°C (HOT). For all OptoTEC™ Series modules, wire is solid, 57 mm-long (2.25 in.) and un-insulated.
