TEC1-12703 40x40mm Thermoelectric Cooler 3A Peltier Module

Thermoelectric Peltier Module TEC1-12703 40x40mm Cooler 3A

The TEC1-12703 40x40mm thermoelectric peltier module is a compact and high-efficiency thermoelectric module that utilizes the advanced Peltier thermoelectric effect. With 127 semiconductor couples packed into a 30mm × 30mm area, this peltier module 12703 delivers excellent heating and cooling performance for electronic applications.

Thermoelectric coolers (TEC) — often called a thermoelectric module — create a temperature difference, generating a hot side and a cold side. This allows the module to either cool or heat components depending on supply polarity. Additionally, you can even generate power using the temperature differential.

This thermoelectric peltier module performs efficiently when the hot side is properly cooled. After the power is applied, the hot side heats up while the cold side cools rapidly. A heatsink is strongly recommended to avoid thermal saturation. Using a CPU heatsink and power supply can make the cold side drop so low that touching it becomes uncomfortable.

A peltier module 12703 works as a small semiconductor-based heat pump. When powered using a 12V DC or regulated voltage up to 15V, it transfers heat from one side to the other. Such thermoelectric module systems are widely used in CPU cooling, CCD stabilization, mini refrigerators, and temperature-controlled equipment.

Also known as: Thermoelectric cooling modules, Peltier modules, TEC modules.

Operating Tips: Do not exceed the rated Imax and Vmax. Ensure proper moisture sealing in final applications.
Life expectancy: 200,000 hours.
Failure rate: approx. 0.2%.

Important Note: The hot side MUST always have a heatsink. Running this thermoelectric peltier module even for a few seconds without a heatsink may damage it.
