Specifications are based on the supplied product information. Actual performance depends on operating conditions, power supply, thermal contact and heat dissipation.
A suitable heatsink and effective heat dissipation are essential.
Attach an appropriately sized heatsink to the hot side and use thermal paste for good thermal contact.
For higher cooling performance, active cooling with a fan or liquid-cooling system may be required.
Without sufficient heat dissipation, both sides can become hot and the module may be permanently damaged.
Use a regulated power supply capable of supplying the required voltage and current.
Do not exceed the module's electrical ratings.
Condensation may occur on the cold side; protect nearby electronics from moisture.
Maximum temperature difference is measured under specific test conditions and is not the same as the achievable cooling temperature under load.
