HiTemp ETX Series ETX25-12-F1-6262-TA-W6
MFG Part Number: 387004930
HiTemp ETX Series Thermoelectric Cooler
The ETX25-12-F1-6262-TA-W6 high temperature, high-performance 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 245.1 Watts when ΔT = 0 and a maximum ΔT of 83.2 °C at Qc = 0.

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.
