OptoTEC Series


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