Description
The SP1848-27145 40x40x3.6mm Peltier Cooler Plate is a thermoelectric module, also known as a Thermoelectric Generator (TEG). While it can perform both cooling and power generation, its specific model name suggests its primary function is to generate electricity from a temperature difference via the Seebeck effect, not to cool something. This compact, 40mm x 40mm module has no moving parts, is sealed for moisture protection, and generates a voltage when there is a temperature differential between its two sides.
Features
- Small and lightweight, convenient for use.
- Designed specifically for power generation.
- Sealed for moisture protection and contain thermal elements formulated for optimum Seebeck power generation.
- High-temperature 150C, with NM static protection.
Specifications:

- Figure of merit (Z): 2.5～3.0×10-3W/℃
- In practical applications, in order to seek greater output voltage and load current, series-parallel combination is often used.
- Power generation sheet size: 40MM long * 40MM wide * 3.6MM thick
- The side with words is close to the cooling side (cold side)
- The wordless side is attached to the endothermic side (hot side)
- The red wire is connected to the positive electrode, and the black wire is connected to the negative electrode. It can generate electricity when there is a temperature difference.
- SP1848-27145 parameters are as follows:
- Temperature difference 20 degrees: open circuit voltage 0.97V, power generation current: 225MA
- Temperature difference 40 degrees: open circuit voltage 1.8V, power generation current: 368MA
- Temperature difference 60 degrees: open circuit voltage 2.4V, power generation current: 469MA
- Temperature difference 80 degrees: open circuit voltage 3.6V, power generation current: 558MA
- Temperature difference 100 degrees: open circuit voltage 4.8V, power generation current: 669MA
- The above values are for reference only. In actual use, the wiring and booster board will cause a loss of current.
- This power generation chip is an export device. Low temperature, residual temperature, temperature difference, power generation, high cost performance, stable performance
