      Description: TA,RT,W6

The ET25-12-F1-6262-TA-RT-W4.5 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 125.4 Watts when ΔT = 0 and a maximum ΔT of 77.9 °C at Qc = 0.
Features
  • High-temperature operation
  • Reliable solid-state
  • No sound or vibration
  • Environmentally-friendly
  • RoHS-compliant

Electrical and Thermal Performance

For maximum performance, be sure to orient the CONTROL side of the TEC against the application to be managed and the AMBIENT side against the heat sink or other heat rejection method. The CONTROL side is always opposite the side with lead attachments. Lead attachment is a passive heat loss and less impactful if located on the side that attaches to the heat exchanger.
