Experience rapid cooling or heating with the TEC1-12706 Thermoelectric Cooler Peltier module. This versatile 12V 6A device, measuring 40x40mm, offers a powerful 55W cooling capacity (Qcmax), making it ideal for a wide range of applications from CPU cooling to custom car drink warmers/coolers.

Simply reverse the polarity to switch between cooling and heating functions, achieving impressive temperature differentials of over 59°C (Tmax at Qc=0). The side with text printed on it is the cooling surface, while the plain, unprinted side is the heat dissipation surface.

Crucial: Important Safety & Usage Instructions

• Heat Sink Required: This Peltier module must be used with an appropriate heat sink or liquid cooling device attached to the heat dissipation surface (the unprinted side). Without proper heat dissipation, the module will quickly burn out.
• Exercise Extreme Caution During Testing: When testing for cooling effect without a heat sink attached, connect power for no more than 1 second and disconnect immediately. Failure to do so will very likely burn out the module. Please test with extreme care.

Constructed from semiconductor material sandwiched between durable ceramic plates, these solid-state devices contain no moving parts, ensuring reliability and a long lifespan. Each module is thoroughly inspected and tested to guarantee optimal performance.
