TEC1-12715 40*40mm

The TEC1-12715 is a 40 × 40 mm Peltier thermoelectric module. When DC current flows through it, one face gets cold and the other gets hot, so it can cool or heat with no moving parts. Its 15 A rating makes it one of the more powerful modules in this size, used in DIY coolers and temperature control projects.

TEC1-12715 Specifications

• Type: single-stage thermoelectric cooler (TEC1)
• Thermocouples: 127 pairs
• Maximum current: 15 A
• Rated voltage: 12 V DC (about 15.4 V maximum)
• Size: 40 × 40 mm
• Operation: reversing the polarity swaps the hot and cold sides

TEC1-12715 Applications

• DIY mini fridges, drink coolers and cool boxes
• Cooling electronics, laser diodes or camera sensors
• Temperature-controlled chambers driven by an Arduino with a MOSFET or H-bridge
• Thermoelectric generator demonstrations in physics classes

What's in the Box

• 1 × TEC1-12715 Peltier module, 40 × 40 mm

Tip: Always mount the hot side on a large heatsink with a fan and thermal paste before powering it; without one the module overheats within seconds and can fail. Use a 12 V power supply that can deliver the high current this module draws.
