71020-501

Annular SH Series SH14-125-045-L1-RT-W4.5 MFG Part Number: 71020-501 Annular SH Series Thermoelectric Cooler Features ● The SH14-125-045-L1-RT-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 70.3 Watts when ΔT = 0 and a maximum ΔT of 70.5 °C at Qc = 0. ● ● ● ● ● Applications Center Hole Precise Temperature Control No sound or vibration Reliable solid-state DC Operation RoHS-compliant ● ● ● ● ● Thermoelectric Coolers for Reagent Storage Thermoelectric Coolers for Handheld Cosmetic Lasers Cooling for Centrifuges Heads-Up Displays, Imaging Sensors Peltier Cooling for Machine Vision 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.
