The TEC1-12703 is a high-performance thermoelectric cooler (TEC) module, designed to transfer heat from one side to the other when DC voltage is applied. Based on the Peltier effect, this compact 30×30 mm module enables active cooling without any moving parts. Ideal for use in CPU/GPU cooling, portable refrigerators, laser devices, climate-controlled seats, and DIY electronics projects. It offers a perfect combination of efficiency, reliability, and low power consumption.
Features:
• Solid-state active cooling — no gas or compressor required
• Compact and lightweight (30mm × 30mm × ~3.6mm)
• Highly reliable with low noise operation
• Suitable for spot cooling or precision temperature control
• Operates efficiently under DC power
• Requires proper heatsink on the hot side for effective operation
• Can also be used in energy harvesting when heated on one side
