The TEC1-04904 Thermoelectric Cooler Peltier 20x20mm is a compact thermoelectric cooling module designed for applications requiring localized cooling and temperature control.
With a small 20x20mm footprint, this module can be integrated into compact electronic devices, sensors, optical equipment and other products where installation space is limited.
As a micro thermoelectric cooler, the TEC1-04904 uses the Peltier effect to transfer heat from one side of the module to the other when DC power is applied. The result is a cold side for cooling and a hot side that requires heat dissipation.
Its compact format makes it suitable for developers looking for a small thermoelectric cooler, mini peltier cooler or miniature thermoelectric cooler for space-constrained applications.
For OEM projects, the module can also be considered as part of a customized thermoelectric cooling module according to the customer's mechanical and thermal requirements.

The module can also be considered for compact medical, analytical and laboratory equipment requiring localized temperature control.
Its small footprint makes the TEC1-04904 suitable for certain portable and compact electronic devices.
The TEC1-04904 works based on the Peltier effect.
When DC current passes through the internal thermoelectric semiconductor elements, heat is absorbed on one side of the module and released on the opposite side.
This creates two different thermal surfaces:
Cold Side → Absorbs Heat
Hot Side → Releases Heat
By reversing the direction of the DC current, the hot and cold sides can also be switched.
Unlike compressor-based refrigeration systems, a micro thermoelectric cooler has no mechanical moving parts and does not require traditional refrigerant circulation. This makes Peltier modules useful for compact cooling, localized temperature control and applications where system size is an important consideration.
However, the hot side must be properly managed. If heat cannot be effectively removed from the hot side, the actual cooling performance of the module can be significantly affected.
The TEC1-04904 has a compact 20x20mm module size, making it suitable for small and space-constrained cooling applications.
Yes. With its compact 20x20mm form factor, TEC1-04904 can be used as a micro thermoelectric cooler for small electronic and temperature-control applications.
It can be considered for electronics cooling, sensor temperature control, optical devices, compact laser systems, semiconductor equipment, analytical instruments and other applications requiring localized thermoelectric cooling.
It can be used for suitable laser cooling applications, provided that the module's electrical and thermal performance matches the laser system requirements.
The hot side requires effective heat dissipation. A suitable heat sink, thermal interface material and airflow or other cooling method may be required depending on the application.
For OEM or customized projects, specifications such as module configuration, wires, wire length, connectors and packaging can be discussed according to project requirements.
Selection should consider the required cooling capacity, operating voltage, current, temperature difference, hot-side temperature, heat dissipation conditions, module dimensions and installation space.
Yes. For micro thermoelectric cooler wholesale, OEM or long-term supply requirements, customers can provide the required quantity and application specifications for further discussion.
