Annular SH Series Thermoelectric Cooler
The SH08-28-05-L1-W4.5 is an annular-style thermoelectric cooler. The hot and cold side ceramics have a circular hole in the center to accommodate light protrusion for optics, mechanical fastening or temperature probe. It has a maximum Qc of 4.8 Watts when ΔT = 0 and a maximum ΔT of 70.5 °C at Qc = 0.
Features
  • Center Hole
  • Precise Temperature Control
  • No sound or vibration
  • Reliable solid-state
  • 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.
