Notes: 1. Maximum voltage at ΔT max and Th=27°C
2. Maximum current to achieve ΔT max
3. Measured by AC 4-terminal method at 25°C
4. Maximum heat absorbed at cold side occurs at Imax, Vmax, and ∆T=0°C
5. Maximum temperature dierence occurs at Imax, Vmax, and Q=0W (ΔT max measured in a vacuum at 1.3 Pa)
6. Designed with arcTEC™ structure.
