UltraTEC™ UTX Series UTX9-28-F2-4040-TA-W6
MFG Part Number: 387004723
UltraTEC™ UTX Series Thermoelectric Cooler
The UTX9-28-F2-4040-TA-W6 is a high-performance thermoelectric cooler that is assembled with advanced thermoelectric materials and can boost cooling capacity by up to 10%. The UltraTEC UTX Series features a higher thermal insulating barrier when compared to standard materials creating a maximum temperature differential (ΔT) of 71.7 °C at Qc = 0. It has a maximum Qc of 196 Watts when ΔT = 0.
  • High heat pump density
  • Precise temperature control
  • Reliable solid-state operation
  • No sound or vibration
  • DC operation
  • 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 HEATSINK 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.
