TEC Microsystems introduces MD TEC Series of thermoelectric modules with high-density pellets placement.

The main feature of this series of miniature TE modules is an increased cooling capacity (up to 25 W/cm2). The distance between pellets is only 200um instead of 400um or 500um in typical thermoelectric modules. Such high-density pellet placement makes it able to fit more pellets within the same size as a standard TEC, and increase TEC cooling capacity.

Modules of the MD Series are suitable for applications where it is required to remove heat from very miniature objects with high power dissipation. And what is important – max dT of MD Series TECs is 70-73C, while widely advertised thin-film TECs have twice less max dT value.

MD Series consists of single-stage and multi-stage TECs(up to 4 stages).

The miniaturization way of MD Series provides a possibility to reduces total construction dimensions. For example, 4-stage MD Series TEC can be easily mounted onto standard TO-8 Header, which was not possible previously with using of standard TECs (because of size factor). Another example is a possibility to fit 127 pellet pairs (254 Bi-Te pellet elements) in single- stage TEC with dimensions only 9.8 x 9.8 mm. This is useful for calorimetry sensing applications, where TEC used as a precise detector.

And of course, MD Series conception opens a way to built very miniature thermoelectric modules for applications, where TEC size is very important, like cooled TOSA applications or cooled TO-46 VCELs.

The most miniature thermoelectric coolers of MD Series are in MD04 Sub-Series. The complete description with parameters and datasheets is available by this link: www.tec-microsystems.com/EN/MD04_TEC_Series.htm[...]
