SP1848-27145 40x40 mm Thermoelectric Peltier Power & Cooling Module
Quantity
Product Description:
This SP1848-27145 thermoelectric Peltier module is a compact semiconductor heat pump that uses the Seebeck and Peltier effects to convert temperature differences into electricity or move heat from one side to the other. It’s ideal for DIY cooling, small thermal management projects, and low-power energy harvesting when there’s a temperature differential. Reliable, silent, and solid-state with no moving parts, this module is perfect for hobby electronics, portable devices, and thermal experimentation.
