Thermoelectric Cooler Peltier 40mm 12v

TEC1 Series Thermoelectric Cooler Peltier Modules – 40mm, 12V

The TEC1 series thermoelectric cooler modules are solid-state devices that transfer heat from one side to the other, creating a temperature difference when powered. Perfect for cooling, heating, or even power generation applications, they are commonly used in CPU coolers, mini fridges, and thermal experiments.

When powered with the correct polarity (red = positive, black = negative), the side with printed text becomes the cold side, while the opposite side becomes the hot side. As long as a temperature difference exists, these modules can also generate electricity.
