12 V TEC1-12705 Thermoelectric Peltier Cooling Module (2 PCS)
Quantity
Product Description:
This pair of TEC1-12705 thermoelectric Peltier cooling chips is ideal for DIY cooling and thermal-control applications. When powered with a 12 V DC supply, these solid-state modules transfer heat from one side to the other, creating a cold side and a hot side without moving parts. Compact, energy-efficient, and versatile, they’re perfect for hobby projects like mini coolers, portable refrigeration, custom electronics cooling, and temperature stabilization systems.
