OptoTEC™ OT Series OT20-32-F0-0808-11-RT-W2.25 MFG Part Number: 430278-508 Legacy Product OptoTEC™ OT Series Thermoelectric Cooler Features Note: This product is not recommended for new designs. This product series has been replaced with the OptoTEC™ OTX Series. The recommended replacement is: MFG Part Number: 387006923 Description: OTX20-32-F0-0808-11-RT-W2.25 ● ● ● ● ● ● Applications Miniature geometric sizes Precise temperature control Reliable solid-state operation No sound or vibration DC operation RoHS-compliant ● ● ● Thermoelectric Cooling for CMOS Sensors Cooling Solutions for Autonomous Systems Heads-Up Displays, Imaging Sensors 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.
