 MFG Part Number: 387004688  
 Description: UTX15-12-F2-4040-TB-W6*  
 The UT15-12-F2-4040-TB-W6 is a high heat flux density thermoelectric cooler. The thermoelectric module is assembled with a large number of semiconducting thermoelectric couples to achieve a higher heat pumping capacity than standard single stage thermoelectric coolers. It has a maximum Qc of 117.1 Watts when ΔT = 0 and a maximum ΔT of 68.9 °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.
