The TES1-03103 Thermoelectric Cooler Module is a compact Peltier device designed for small-scale cooling and thermoelectric experimentation applications. Operating at up to 3V DC with a maximum current of 3A, it provides efficient heat transfer using solid-state thermoelectric technology with no moving parts. The module creates a temperature difference between its two ceramic surfaces, making it suitable for cooling systems, portable devices, scientific projects, and educational demonstrations of the Peltier effect. Its compact 15 × 15 mm form factor allows easy integration into space-constrained electronic and thermal management designs.
