What it is

The Unique-Bargains TES1-12704 is a 12V 36W thermoelectric Peltier module measuring 30x30x3.5mm. It draws 4A and creates a temperature differential of about 65C or 149F when powered at 5.78V. The white ceramic plate suits hobbyist cooling experiments and small-scale thermal management projects.

Before ordering

Confirm you have a DC power source capable of delivering 12V at up to 4A. A substantial heat-sink must be ready for the hot side before any power is applied. The module will overheat and fail within seconds if energised without adequate thermal dissipation on the warm face.

Build integration

The 30cm lead wires allow flexible placement inside enclosures or test rigs. The compact 30mm square footprint fits tight spaces where compressor cooling is impractical. It requires a mating cold plate or target surface and a robust hot-side heat-sink with airflow to maintain the differential and prevent thermal runaway.
