Five square white ceramic Peltier modules with red and black wires on a dark surface

SXDOOL

SXDOOL TEC1-12705 Peltier Module 5pcs 12V 5A 40x40mm

SKU CH-6FPK-N626K

A set of five thermoelectric coolers rated at 12 V, 5 A with a 56 W maximum heat-pumping capacity each

  • Silent operation with zero vibration from solid-state design
  • Generates electricity when a temperature difference is applied
  • Compact 40 x 40 mm footprint fits tight spaces
  • Moisture-resistant sealed construction protects the module
  • Five modules per lot for multi-zone cooling projects

Five-module thermoelectric kit

This pack contains five TEC1-12705 Peltier modules rated for 12 V and 5 A operation. Each 40 x 40 x 4 mm cell uses 127 thermocouples and is fully sealed against moisture. The units suit hobbyists building custom cooling loops, experimental generators or compact thermal cyclers.

Silent solid-state heat pumping

With no moving parts the modules produce zero noise or vibration while moving up to 56 W of heat at the rated current. Maximum voltage is 15 V although typical use stays at or below 12 V, and the hot-side temperature limit is 67 °C. Copper-and-aluminium heatsinks are recommended to keep the hot side within that limit.

Ready for immediate assembly

The lot ships as five pieces in a single 15 cm cube weighing 1.0 kg. No drivers, software or mounting hardware are included, so builders must supply their own thermal interface material, power regulation and mechanical clamping. Users needing a controlled controller board or pre-wired harness will need a separate purchase.

Questions about this item

How do I install the TEC1-12705 module and what step is often missed?

Apply thermal paste to both 40x40mm faces, clamp the module evenly between a cold plate and a heatsink, then connect to a 12 V supply limited to 5 A. The step most people skip is tightening the mounting screws gradually in a cross pattern so pressure stays uniform across all 127 couples.

What maintenance or replacement will the TEC1-12705 need over time?

The module itself has no moving parts and is fully sealed against moisture, so it requires no scheduled maintenance. Plan to replace the thermal interface material every one to two years because pump-out under thermal cycling degrades contact and raises the hot-side temperature.

What limit appears first when the TEC1-12705 runs continuously at full load?

The 67 °C maximum temperature difference (Tmax) is reached first. At 5 A and 12 V the module moves up to 56 W of heat, so the hot side must stay below 67 °C above the cold side or cooling capacity collapses and the device can overheat.
