      Description: ETX4-7-F1-2020-TB-EP-W8
The ZT4-7-F1-2020-TB-EP-W8 is a high performance thermoelectric cooler that achieves a higher temperature differential than standard single stage thermoelectric coolers. It has a maximum Qc of 18.6 Watts when ΔT = 0 and a maximum ΔT of 71.7 °C at Qc = 0.
Features
  • High temperature differential
  • 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.
