Catalogue sources: HB TEC1-12706 Rev. 2.03 and Roßmann RO6.0-51.4. These references do not establish equivalence with the SR model.
Qmax and ΔTmax describe different limiting conditions and are not achieved simultaneously. Select the operating point according to the heat load, hot-side temperature and actual temperature difference.

Application concepts
to validate with the actual system
Localised cooling
Evaluate applications in confined spaces and provide adequate hot-side heat rejection.
Replacement parts and prototyping
Compare dimensions, thickness, leads, sealing and ratings with the original part. Test samples under the actual operating load.
Components that make the system work together
Temperature control requires a current-limited driver, feedback sensor, thermal interface material and suitable hot-side cooling. The module alone does not determine the system's temperature accuracy.
Check polarity and the hot/cold sides before use. Mount on flat surfaces with uniform clamping force, and assess condensation when cooling below ambient temperature.
