OptoTEC™ MBX Series

Supports high-temperature applications with compact geometric space constraints

The MBX Series of micro thermoelectric coolers support high-temperature applications with compact geometric space constraints. MBX delivers precise temperature stabilization under changing environmental conditions. The MBX Series offers micro footprints as small as 1.5 x 1.1mm with thicknesses down to 0.65mm. The packing fraction for thermoelectric materials enables high heat pumping densities up to 43 W/cm² at lower operating currents than traditional thermoelectric coolers.
