ST-127-1.4-4.0 is our least powerful single-stage thermoelectric module, in the 40 x 40 mm footprint, intended for use with 12 to 15-volt DC power sources. This module is best used in applications where maximum coverage is desired but loads (or DT's) are not substantial. This is often an excellent choice if temperature stabilization near ambient is desired or when space for a hot-side heat-sink is limited. Also available with porch, metallized and tinned surfaces and in strings from 2-12 modules long.
ST-127-1.4-4.0 may be used for cooling, heating and temperature stabilization and is employed in a wide range of applications including electro-optic/telecommunications, lab/scientific/biomedical, consumer, aerospace/military and test.
- 100% QC. A certificate of conformance (CofC) will be issued upon request.
- Maximum operating temperature +150°C
Melting point of internal solder (Pb/Sn): 183°C
Antidiffusion barriers prevent solder migration
- Height, flatness and parallel variance: ± 0.02mm (lapping to a close height tolerance ± 0.01mm available)

Module Characteristics and Value Descriptions:
Imax is the maximum (optimal) input current in amperes
Vmax is the maximum input voltage in volts when the current is optimal (Imax)
Qmax 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.
DTmax or DTmax 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.
