56995-503

Ceramic Plate Series CP2-31-10-L1-RT-W4.5 MFG Part Number: 56995-503 Ceramic Plate Series Thermoelectric Cooler Features ● The CP2-31-10-L1-RT-W4.5 is a high-performance and highly reliable standard Thermoelectric Cooler. Assembled with Bismuth Telluride semiconductor material and thermally conductive Aluminum Oxide ceramics. It has a maximum Qc of 18.8 Watts when ΔT = 0 and a maximum ΔT of 70.5 °C at Qc = 0. ● ● Applications Compact geometric sizes 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.
