Peltier Thermoelectric Cooler Module TEC1-12706 – 12V 3A, 40x40mm

The TEC1-12706 Peltier thermoelectric cooler module is a high-efficiency solid-state heat pump that transfers heat from one side to the other when powered. It’s perfect for DIY cooling systems, temperature control experiments, and electronic component cooling.

When a 12V DC supply is applied, one side becomes cold while the opposite side heats up — making it ideal for compact cooling or thermal regulation applications.
