The PCX4-12-F1-3030-TA-RT-W6 is a high-performance thermoelectric cooler from the PowerCycling PCX series, engineered for applications requiring fast temperature changes. At a hot-side temperature of 27°C, it delivers a maximum cooling power (Qcmax) of 34.7 Watts and achieves a maximum temperature differential (ΔTmax) of 73.6°C. The module is specially constructed with Al2O3 ceramic and 232°C SbSn solder to reduce stress on its internal elements during operation and is sealed with RTV silicone. It is ideal for demanding applications such as molecular diagnostics (PCR), point-of-care testing devices, and thermal test sockets.
