Laird Thermal Systems OptoTEC OTX/HTX Series thermoelectric coolers

The Laird Thermal Systems OptoTEC OTX/HTX Series miniature thermoelectric coolers offer high-heat-pumping capacity and temperature stability for space-constrained optoelectronic applications.

Featuring precise temperature controls with up to 10 W of cooling power, the series maintains a temperature differential of up to 82°C at Qc = 0, with a hot side temperature at 50°C. The OTX thermoelectric cooler is designed for operating temperatures up to 120°C, while the HTX thermoelectric cooler uses a higher-temperature construction to operate in temperatures up to 150°C.

Featuring next-generation thermoelectric materials, the series is said to offer a 10% boost in cooling capacity, greater temperature differential and higher efficiency than standard thermoelectric coolers. It also surpasses Telcordia GR-468 CORE qualifications to withstand harsh mechanical and environmental test standards and manufacturing process controls, for 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.
