Thermoelectric coolers for legacy designs

The ThermaTEC™ HT Series and OptoTEC™ HOT Series of thermoelectric coolers have been superceded by the HiTemp ET Series for designs operating at high temperatures. The HiTemp product line is available in more configurations as well as drop-in replacements for applications that operate in temperatures above 80°C or that require both heating and cooling mode (reverse polarity). Also, some of the OptoTEC™ OT Series have been retired in favor of other part numbers. Listed below are legacy datasheets and available distributor stock, as well as links to replacement product pages and distributor stock.
