The ET08-66-F0-1009-11-W2.25 high temperature thermoelectric cooler uses Laird Thermal Systems' enhanced Thermoelectric Module construction preventing performance degrading diffusion, which is common in standard grade thermoelectric coolers operating in high temperature environments exceeding 80 °C. It has a maximum Qc of 3.7 Watts when ΔT = 0 and a maximum ΔT of 77.9 °C at Qc = 0.
- High-temperature operation
- Reliable solid-state
- No sound or vibration
