MFG Part Number: 7050040-502
PolarTEC™ PT Series Thermoelectric Cooler
The PT6-12-F2-4040-TA-RT-W6 is a porch-style thermoelectric cooler. The hot side ceramic has an extended edge, which allows for a strong lead attachment to accommodate the wiring of multiple thermoelectric coolers into an array. It has a maximum Qc of 50.6 Watts when ΔT = 0 and a maximum ΔT of 70.5 °C at Qc = 0.
Features
  • Strong lead attachment
  • 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 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.
