TEC1-12709 40×40mm 9A Thermoelectric Cooler Module
The TEC1-12709 is a 40×40mm solid-state thermoelectric cooler (Peltier) module designed for 12V DC operation, capable of handling up to 9A for active heat transfer. It is ideal for integration into custom cooling systems, portable refrigeration, and thermal management projects requiring precise temperature control.
Features
- 127 semiconductor couples for efficient thermoelectric cooling/heating
- Rated for 12V DC operation with a maximum current of 9A (130W max power)
- Solid-state, vibration-free operation with simple polarity reversal for heating/cooling mode switch
- Compact 40mm x 40mm footprint with 25cm pre-attached power leads
- Mandatory heat sink requirement on the hot side for stable, long-term operation

The TEC1-12709 operates on the Peltier effect, where applying a DC voltage across the module causes heat to be pumped from one ceramic face to the other, creating distinct hot and cold sides. This solid-state device contains 127 bismuth telluride semiconductor couples, offering reliable, maintenance-free thermal transfer without moving parts.
For optimal performance and to prevent thermal runaway, the hot side must be actively managed with an appropriate heatsink and, often, forced-air cooling. The module’s longevity is rated for approximately 200,000 hours, making it suitable for continuous-duty applications in controlled environments.
