The 430875-503 is a ceramic plate series thermoelectric cooler (CP14-199-045-L1-W4.5) designed for high-performance and reliable cooling in compact applications. Assembled with Bismuth Telluride semiconductor material and thermally conductive Aluminum Oxide ceramics, it delivers a maximum cooling capacity (Qc) of 111.8 Watts at zero temperature differential (?T = 0) when the hot side is at 27 °C, and achieves a maximum temperature differential of 70.5 °C at zero cooling load. The module operates on DC power with a maximum current of 8.6 Amps and maximum voltage of 21.7 Volts at maximum temperature differential, featuring a module resistance of 2.35 Ohms at 27 °C hot side temperature. It is RoHS-compliant and rated for a maximum operating temperature of 80 °C. Common applications include reagent storage cooling, handheld cosmetic laser systems, centrifuge cooling, and machine vision thermal management.
