Thermoelectric coolers

Print version

MD Series of Single & Multistage TE Modules

   MD Series thermoelectric coolers are based on RMT high-density pellets placement technology. The distance between elements is reduced, comparing with regular technology TECs. This allows to reduce the size of thermoelectric cooler keeping the same performance as regular type, or to increase the cooling capacity up to 100% with the same size as regular TEC has. There are six MD Series available: MD015, MD02, MD03, MD04, MD06 and MD10. The difference between series is in internal pellets cross section, performance parameters range and overall dimensions.

HD pellets placement technology:
-The increasing of TEC cooling capacity without size change
-Switching to smaller form factor keeping the same performance
MD Series is recommended for applications in small form factors (TO46 and TO56 and smaller)


   Thermoelectric cooler of MD Series are based on RMT HD pellets technologies with high density pellets placement.

• MD04, MD06 and MD10 Series are based on HD technology with about 250 pellets per 1 cm2 density.

• MD03 Series of low current TECs is developed specially for cooled TOSA applications and is based in RMT advanced HD technology (more than 400 pellets per 1 cm2).

• MD02 Series has a range of TEC with 1100 pellets per 1 cm2.

• MD015 Series has a unique combination of a miniature cross section of pellets and a distance of 100 μm between them, which allows the density of 1600 pellets per 1 cm2.

   Each TEC Series has its own advantages depending on application conditions and requirements.

Hint: HD technology TECs are not a “must-do” replacement for regular types. The decision which thermoelectric cooler to apply - from RMT standard Series or MD - depends a lot from application. Standard and HD technology thermoelectric coolers may have same dimensions by different performance and power consumption. The best choice depends from application conditions and requirements. Please, contact RMT Ltd to get the precise estimations for your application or use TECCad (Windows) software.
