## Description

Turn a temperature difference into electricity. Hold one side of this module against something warm, keep the other side cool, and it generates a usable voltage with no moving parts at all. It is a tidy way to show energy conversion happening on the bench, and it is the same component behind real waste-heat harvesting, from wood stove fans to spacecraft power supplies. How to use it The face with the printed text is the cold side. The blank face is the hot side. Red lead is positive, black lead is negative. The bigger the temperature difference across the module, the more you get out of it: Temperature differenceOpen-circuit voltageCurrent 20°C0.97V225mA 40°C1.8V368mA You will want a heatsink on the hot side to keep that difference up. Without one, both faces drift towards the same temperature and the output falls away, which is a useful lesson in itself. Specifications Model: SP1848-27145 Size: 40 × 40 × 3.4mm Lead length: approximately 300mm Colour: white No moving parts, long service life A note for teachers This is a generator, not a cooler. A Peltier module (TEC) is the same physics run backwards: put power in, get a temperature difference out. This one is built for the other direction, which is what you want when the task is about harvesting energy rather than moving heat. If you need the cooling direction instead, look at our Peltier modules.

**Product Type:** Thermoelectric Generator
