Laird Technologies, Inc. (St. Louis, MO) has released its eTEC(TM) Series Thermoelectric Module (TEM) product line. The eTEC Series of TEMs enable high-powered optoelectronics to maintain peak performance by stabilizing the temperature of the device during operation. Constructed with Bismuth Telluride thin film technology and thermally conductive Aluminum Nitride ceramics, the eTEC Series is designed for higher voltage and lower, sub 10 Watt heat pumping applications. The ceramic substrates are gold metallized to allow the product to be embedded into densely packed optoelectronics. The thin film eTEC TEMs have heat pumping densities ranging from 75 to 90 W/cm2 at an ambient temperature of 25°C.
