TM-127-1.0-4.0 TE Cooler Technical Data

QC vs. I Curve

TM-127-1.0-4.0 is a multi-purpose single-stage thermoelectric module is our most popular 30 x 30 mm module intended for use with 12 to 15-volt DC power sources. It has a substantial cooling capacity in a small footprint and works well with a variety of economical heat-sinks.

TM-127-1.0-4.0 may be used for cooling, heating and temperature stabilization and is employed in a wide range of applications including consumer, lab/scientific and biomedical, telecommunications, electro-optic, aerospace and test. Also available with porch and/or metallized and tinned surfaces.

Maximum operating temperature +200°C
Anti-diffusion barriers prevent solder migration

This module may be used for high temperature and/or thermal cycling applications

Module Characteristics and Value Descriptions:

I_max is the maximum (optimal) input current in amperes

V_max is the maximum input voltage in volts when the current is optimal (I_max)

Q_max is the maximum amount of heat the module is capable of pumping. This value is achieved when there is no difference in the temperature (DT=0) on the modules two surfaces. If your application requires cooling, the heat pumping capacity will be less.

DT_max or DT_max is the maximum temperature differential between the hot and cold side of the module with no heat load (Q=0)
As the thermal mass of the object to be cooled increases the DT becomes fewer degrees until Qmax is reached and DT=0.
