Laird Thermal Systems has released its enhanced OptoTEC OTX/HTX series of miniature thermoelectric coolers for high temperature environments in industrial, telecommunications, automation and photonics applications. The OptoTEC OTX/HTX series uses next-generation thermoelectric materials, providing a 10% increase in cooling capacity compared to standard thermoelectric coolers, resulting in greater temperature differences and higher efficiency.
High-performance solid-state cooling equipment is specifically designed to control the temperature of thermal-sensitive optoelectronic components used in applications such as laser diodes, lidar, optical transceivers, CMOS and infrared sensors.
The product line is Telcordia GR-468 CORE certified to withstand demanding mechanical and environmental testing standards and has improved manufacturing process controls to ensure high repeatability and long life operation. With a footprint as small as 3mm X 4mm, the series offers high thermal pumping capacity and enhanced temperature stability for optoelectronic applications with tight geometric space constraints. Providing up to 10W of cooling power, the series maintains a temperature difference of up to 82C δ Tmax (Qc = 0) and a hot side temperature of 50℃
Andrew Dereka, Director of Thermoelectric Products at Laird Thermal Systems, said, "It is not easy to stabilize photovoltaic components at high temperatures. The OptoTEC OTX/HTX series uses new thermoelectric materials and enhanced process control to meet the needs of the optoelectronics industry by providing higher cooling performance at a miniature size."
There are two versions of the series. The OTX thermoelectric cooler has a maximum operating temperature of 120℃, while the HTX thermoelectric cooler has a higher temperature construction and can operate up to 150℃. Custom configurations are provided to suit metallization, tin front, ceramic modes and solder posts.
