Laird’s New Tlam OptoTEC Series Moves Heat in a Different Direction

Laird has announced a new series of miniature thermoelectric modules (TEMs) built using Laird Tlam thermally conductive circuit boards instead of traditional ceramic-based circuit boards. The Tlam OptoTEC® series is designed for applications where temperature stabilization of sensitive optical components in photonics, telecom, medical and consumer markets is critical. The use of the circuit board improves the heat pumping capabilities of the device while providing excellent heat spreading, improved reliability and lower cost in high volume when compared to traditional heat removal systems.

The Tlam OptoTEC series includes seven new modules that can create a temperature differential (ΔT) of up to 67°C and pump from 1.5 to 9.0 watts of heat at an ambient temperature of 25°C. At 85°C, the series can create a ΔT of 77°C and pump 1.6 to 9.9 watts of heat. The modules have passed Telcordia GR-468-CORE Issue 2 reliability qualification testing and are easily customizable to accommodate alternate sizes, heat pumping capacities, unique circuit patterns and pre-tinning requirements.
