  • Product Code: Thermal Electric SP1848
  • Availability: In Stock

Generate electrical energy. The only requirement is that each face of the device must be exposed to different temperatures; a "hot" side and a "cold" side. The greater the temperature difference, the more power generated. While all of our thermoelectric devices will generate power.


Specification :

  • Model: SP1848-27145
  • Size: 40mm x 40mm x 4mm
  • Side with the word is near to the cooling surface (cold side)
  • Side with No word is near to the endothermic side (hot side)
  • Red wire to positive and black wire to negative, as long as there is a temperature difference,it can generate electricity.
  • These devices must be used in conjunction with a heat sink to avoid burned
