TEC1-12706 Thermoelectric Peltier Cooler Plate

TEC1-12706 Thermoelectric Peltier Cooler Plate is a robust solid-state heat pump that provides reliable, localized cooling or heating without the use of refrigerants or mechanical compressors. Utilizing the Peltier effect, this compact module actively transfers heat from one side (the cold side) to the other (the hot side) when you apply a DC voltage. Therefore, connecting the hot side to an effective heat sink is crucial for efficient operation. The “12706” designation indicates the number of PN couples (127) and the maximum current rating (6 A), making it highly suitable for medium-power thermal management tasks. Consequently, engineers and hobbyists widely incorporate the TEC1-12706 into precision cooling systems where space constraints and noise are significant factors.

Key Features:

• Solid-State Cooling: Operates silently and without moving parts, offering superior longevity and shock resistance compared to conventional cooling methods.
• High Cooling Capacity (Q_max): Achieves a maximum cooling capacity of approximately 50 Watts, suitable for rapidly cooling small volumes or components.
• Precise Temperature Control: Easily reversible by changing the polarity of the DC voltage, allowing for rapid thermal cycling and fine temperature regulation.
• Sealed Construction: The module features sealed edges to protect the semiconductor elements from moisture and dust, enhancing durability.
• Compact Form Factor: The standard 40 mm x 40 mm square footprint fits easily into various consumer electronics and industrial devices.

Pinout and Wiring:

• Red Wire: Connect to the positive (+) terminal of the DC power supply.
• Black Wire: Connect to the negative (−) terminal of the DC power supply.
• Cooling Operation: When the red wire is positive and the black wire is negative, the side with the visible text/label will become hot, and the opposite side will become cold.
• Heating Operation: Reverse the polarity (Black to + and Red to −) to heat the side with the visible text/label.
• Wiring Note: You must use a dedicated, current-regulated 12 V power supply capable of safely delivering the 6 A maximum current.
