OptoTEC OTX/HTX Series of Miniature Thermoelectric Coolers

Sept. 23, 2021
OptoTEC OTX/HTX Series of Miniature Thermoelectric Coolers from Laird Thermal Systems feature next-generation thermoelectric materials.

The enhanced OptoTEC OTX/HTX Series of Miniature Thermoelectric Coolers is designed for high-temperature environments found in telecom, industrial, autonomous, and photonics applications. Featuring next-generation thermoelectric materials, the series offers a boost in cooling capacity, greater temperature differential, and higher efficiency than standard thermoelectric coolers.


The high-performance, solid-state cooling devices are specifically designed to control the temperature of heat-sensitive optoelectronic components used in laser diodes, optical transceivers, LiDAR, CMOS, and Infrared Range (IR) sensor applications.


In footprints as small as 3000 x 4000 ?m (3 x 4 mm), the series offers high heat pumping capacity and improved temperature stability for optoelectronic applications with tight geometric space constraints. The product series offers up to 10W of cooling power. It has passed Telcordia GR-468 CORE qualification to withstand harsh mechanical and environmental test standards, and manufacturing process controls have been enhanced to ensure high repeatability and long-life operation.


The OptoTEC Series is available in two versions. The OTX thermoelectric cooler is designed for operating temperatures up to 248°F (120°C). The HTX thermoelectric cooler uses a higher temperature construction to operate in temperatures up to 302°F (150°C). Custom configurations are available to accommodate metallization, pre-tinning, ceramic patterns, and solder posts.
