TM 127-1.4-6.0 Thermoelectric Cooling Module
Specifications with Thot = 27 °С
40 x 40 x 3.95
TM-127-1.4-6.0 is a solid performer and our most popular 40 x 40 mm multi-purpose single-stage thermoelectric module. It’s the perfect balance between good cooling capacity with the ability to use a variety of economical (extruded) heat-sinks that can keep the hot-side temperature from becoming unreasonably high.
May be used for cooling, heating and temperature stabilization in a wide range of applications including refrigeration, consumer goods, medical, analytical, laboratory & scientific instruments, chillers, telecommunications, electro-optics, industrial and military.
Operating temperature range: -50 °C ~ +200 °C
Available with metalized (and tinned) surfaces;
In strings, of your design or ours, from 2-12 modules long;
For thermal cycling. Contact us for details.

Performance Curves with Th 27 °C
In a forced convection assembly the hot-side (Th) of the TEC is in contact with a heat-sink that will always have a temperature above ambient. This curve is particularly appropriate for the many applications operating in an ambient around 22 °C with a typical 5 °C increase in the temperature of the heat-sink.
Performance Curves with Th 50 °C
In a natural or forced convection assembly the hot-side (Th) of the TEC is in contact with a heat-sink that will always have a temperature above ambient. This curve is particularly appropriate for natural convection applications operating in an ambient around 20 °C with a 30 °C increase in the temperature of the heat-sink, a forced convection assembly within an instrument with marginal ventilation or an approximately 45 °C ambient temperature.
