Typical Thermoelectric Module tolerances in mm Illustration  

Imax is maximum current at ΔTmax

Umax (AKA Vmax) is maximum voltage at ΔT max

Qmax is maximum cooling capacity at Imax, Vmax and ΔT = 0°C

ΔTmax is maximum temperature difference at Imax,Vmax and Q = 0W

 
Typical Module Properties

Maximum operating temperature: +200°C (2-Stage and Round Modules +100°C).

Melting point of internal solder (Sn/Sb 5%): +235°C (2-Stage and Round Modules +138°C).

Lead wires - Stranded tinned copper PVC insulated - see data sheets for gauge (Other wire available).

Height tolerance: ± 0.025 mm (Lapping to a close-height tolerance of ± 0.01 mm available).

Flatness and Parallel variance not more than: 0.05mm.

Alumina Oxide Ceramics: Al2O3

Maximum compressive load: 1MPa

ΔTmax is measured in vacuum 1.3Pa

A Thermal Cycling version of each single-stage module, with a patented adhesive process between the copper pads and ceramics, is available.

Modules are available in custom arranged strings from 2-12 modules long. Metalized and/or tinned surfaces are also available.
