TM 31-1.0-4.0 is a general purpose single-stage thermoelectric module, with mid-range cooling capacity in the 15 x 15 mm footprint. Slightly more powerful than the 3-amp version of this module, TM 31-1.0-4.0 provides roughly 20% more cooling capacity with the ability to cool or stabilize slightly greater loads.

TM 31-1.0-4.0 may be used for cooling, heating and thermal stabilization and is employed in a wide range of applications including including medical, analytical, laboratory & scientific instruments, electro-optics, telecommunications and military. A version for thermal cycling is available.

In electro-optic and photonic applications, TM 31-1.0-4.0 is commonly used to maintain a constant temperature in order to stabilize the wavelength of a diode, detector or sensor.

Performance Curves

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.
