TM-127-1.4-6.0 Thermoelectric Module Technical Data

QC vs. I Curve

TM-127-1.4-6.0 is a multi-purpose single-stage thermoelectric module that is our most popular 40 x 40 mm module intended for use with 12 to 15-volt DC power sources. Although it doesn't have the greatest heat pumping capacity (Qmax) in this footprint, it is a solid performer. From a design perspective, it can be used with a variety of economical extruded or other economoical forced convection heat-sinks, without the hot-side temperature becoming unreasonably high.

TM-127-1.4-6.0 may be used for cooling, heating and temperature stabilization and is employed in a wide range of applications including consumer, lab/scientific/biomedical, industrial, telecommunications, military, aerospace and test. Also available with porch, metallized and tinned surfaces and in strings from 2-12 modules long.

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

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

Option Suffix designations:
Anti-corrosion Potting "P"
Epoxy edge sealing "E"
Lapping to ą 0.01mm "L"
(for example ST-127-1.0-3.0"PE")

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.
