TM 71-1.4-6.0 Thermoelectric Cooling Module
Specifications with Thot = 27 °С
30 x 30 x 3.95
TM 71-1.4-6.0 is a popular multi-purpose single-stage thermoelectric module with a 30 x 30mm footprint. Typically used with 5 to 8 Volt DC power sources.
TM 71-1.4-6.0 can be used with a very wide variety of economical extruded heat-sinks without the hot-side temperature becoming unreasonably high. It’s also frequently used in strings. For example, two connected in series can be operated from a 12V source (or 15V). Four in series are operated with a 24V source, etc. A combination of parallel strings of modules in series allows coverage of a large surface area.
May be used for cooling, heating and thermal stabilization and is employed in a wide range of applications including electro-optic/photonic, fiber optic, aerospace/military, telecommunications. A version for thermal cycling is available.
Operating temperature range: -50 °C ~ +200 °C
Available with metalized and tinned surfaces.

Performance Curves (click image for enlargement)
Thermoelectric module performance curves are graphical representations showing the relationships between power applied and net cooling for a specific TE module.
Performance curves are valuable tools for quickly determining if a TE module is a suitable COOLER for an application; learning what power is required for an appropriate module to reach the desired temperature and heat pumping capacity; and to provide the basic information necessary for proper assembly design.
Curves with Th = 27 °C indicate what to expect operating in ambient temperatures around 20 °C (70 °F) with an operational "hot-side" temperature or Th about 7 °C above ambient.
Curves with Th = 50 °C are for outdoor, box-in-box, and other applications with ambient temperatures in the 40-50 °C range.
