TE Coolers

Originally MD03 Series was developed as a successor of MD04 Series, mainly with a focus on modern trends in the telecom industry - lower current, higher voltage.  Single-stage thermoelectric coolers in MD03 Series are primarily optimized for telecom applications, especially TO-can TOSA and similar products.  MD03 TECs are based on our Advanced HD technology with 400 BiTe pellets per cm2 density.  By Performance-Price factor single-stage thermoelectric coolers from MD03 Series take the golden mean between MD04 and MD02 Series.  Reasonable balance between TEC current and voltage, small size and affordable pricing make MD03 thermoelectric coolers optimal for telecom applications with a  price pressure factor.  The standard and most common single-stage types from our MD03 Series are listed in the table below.  All thermoelectric coolers are assembled using RoHS compliant Sn-Sb solder with a melting temperature Tmelt=230ºC.  Thermoelectric coolers of MD03 Series all meet Telcordia GR-486 standard requirements.  A wide range of TEC manufacturing options is available.  Detailed TEC drawings, 3D models, performance plots and estimations for particular application conditions can be provided by request.
