From the shop's description

DC Fan 5V 0.2A 50x50x20mm The DC fan rated 5 volts and about 0.2 amps in a 50×50×20 mm form factor is a compact axial blower typically used for cooling small electronic components. Its modest size—50 mm square with a depth (thickness) of 20 mm makes it suitable for constrained spaces inside enclosures, small devices, or modules where airflow is needed but space is limited. The fan’s motor and blade assembly are housed in a plastic or polymer frame, which provides structure, mounting points, and some protection against mechanical damage. When powered, the fan draws a moderate current (0.2 A at 5 V) to spin the blades, moving air from one side to the other. The airflow helps carry heat away from hot components, lowering temperatures and improving reliability. Noise is present but relatively low (depending on blade design and bearing type), and vibration is usually mild if mounted properly. Wiring is simple: a positive and negative lead, insulated and routed out of one corner or side. Because it operates at 5 V, this fan can often be powered directly from small DC supplies, USB-powered circuits, microcontrollers, or battery sources. Its lifespan depends on bearing type, duty cycle, ambient temperature, and cleanliness (dust/clog buildup can degrade performance). The fan’s depth (20 mm) allows reasonably sized blades, which helps in achieving better airflow for its size. Overall, it offers a balance: small footprint, moderate cooling capability, and relatively simple integration into small systems where 5V supply is available. Features: Operates from a low DC voltage (5 V), compatible with USB, microcontrollers, or small DC supplies. Axial airflow configuration for efficient cooling in compact designs. Plastic or polymer frame with built-in mounting holes for easy installation. Blade design optimized for airflow vs noise trade-off. Simple two-wire lead (positive/negative), minimal wiring. Often uses brushless motor (if typical), giving longer lifespan and lower maintenance.
