Thermoelectric coolers for optoelectronic systems

25 August 2021 Circuit & System Protection

Featuring next-generation thermoelectric materials, the OptoTEC OTX/HTX Series of thermoelectric coolers from Laird Thermal Systems offers a 10% boost in cooling capacity, greater temperature differential and higher efficiency than standard thermoelectric coolers.

Available from Mouser, these miniature thermoelectric coolers offer high heat-pumping capacity and improved temperature stability for space-constrained optoelectronic applications. Featuring precise temperature controls with up to 10 Watts of cooling power, the OptoTEC OTX/HTX Series maintains a temperature differential of up to 82°C at QC = 0, with a hot-side temperature at 50°C. The OTX is designed for operating temperatures up to 120°C, while the HTX uses a higher-temperature construction to operate in temperatures up to 150°C.

The coolers surpass Telcordia GR-468 CORE qualifications to withstand harsh mechanical and environmental test standards and manufacturing process controls, ensuring high repeatability and long-life operation. The tiny devices, available in footprints as small as 3,3 x 4,9 mm, are specifically designed to control the temperature of heat-sensitive optoelectronic components used in optical transceivers, lidar, CMOS and infrared (IR) range sensor applications.
