HiTemp ET Series ET20-31-F1A-0909-TB-W2.25 MFG Part Number: 430550-502 Legacy Product HiTemp ET Series Thermoelectric Cooler Features ● Note: This product is not recommended for new designs. This product series has been replaced with the HiTemp ETX Series. The recommended replacement is: MFG Part Number: 387006921 Description: OTX20-31-F2A-0909-TB-W2.25 ● ● ● ● Applications High-temperature operation Reliable solid-state No sound or vibration Environmentally-friendly RoHS-compliant Peltier Cooling for Refrigerated Centrifuges Peltier Cooling for Machine Vision Thermoelectric Cooling for CMOS Sensors Cooling Solutions for Autonomous Systems Peltier Cooling for Digital Light Processors ● ● ● ● ● ● 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.
