Reference description:
Product model: SP1848-27145 SA.
Principle: The Seeback Effect
Use environment: -60~125
Product raw material: bismuth telluride
Ingot specifications: Ф30mm L-30cm Thermoelectric parameters: Thermoelectric force (a): ＞190×μV/℃ Electrical conductivity (σ): 850～1250Ω-1.cm-1 Thermal conductivity (K): 15～16×10 -3-W/℃cm 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.

Size: 40MM length * 40MM width * 3.6MM thickness
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

Product features:
The power generation sheet can also be used for cooling. It needs to be connected to a 12v6A DC power supply for cooling, but it is not recommended for cooling.

Package include: 1pc
