MicroTECs for extra space - thermoelectric coolers on special thin ceramics
Jul 15, 2010
RMT Ltd introduce special solution for applications with micro thermoelectric coolers. Miniature thermoelectric coolers with only 0.6mm height are available. This special ultra-thin solution is developed for LD applications with limited packaging space. The lowest height of typical thermoelectric coolers is around 0.9mm.В But laser diodes on TO-46 headers or TO-style TOSA have very limited space for integrating of TE cooler. Even additional 100-200 microns of space may be critical for components packaging. With special thin ceramics TEC Microsystems provides now up to 300um of extra space for mounting, keeping TEC height at 0.6mm only.

New ultra-thin solution is mainly oriented for very miniature thermoelectric coolers of MD04 Series, usually used for standard TO-46, TO-56 and customized miniature TO-style headers. Special thin ceramics can be applied for both ceramics plates or for one side only. This option gives additional flexibility with final product packaging.

Ultra-thin ceramics solution is available for all standard thermoelectric coolers, optimized for cooled TOSA applications. The complete list of TE coolers for telecom TOSA is available by this link. Thin ceramics solution can be requested as the additional option.
