TEC1-12704 Peltier Module – 4A

The TEC1-12704 Thermoelectric Cooler Module is a semiconductor-based Peltier device designed for compact cooling and heating applications. It operates using the Peltier thermoelectric effect and contains 127 semiconductor couples within a 40 × 40 mm ceramic plate. When powered with DC voltage, the module transfers heat from one side to the other, creating distinct hot and cold surfaces. Designed for reliable thermal transfer, it supports applications such as CPU cooling, portable refrigeration, temperature control systems, laboratory equipment, and thermoelectric power experiments. The module is compatible with heat sinks and water-cooling systems for improved thermal performance and operational stability.
