Micro fan for compact devices

The ADDA AD0205LB-D53 is a 25 mm square micro fan designed for 5 V DC operation. It draws 0.04 A through a three-pin connector with three wires. The black frame houses a ball bearing for reliable rotation in tight spaces.

Suited for embedded and networking hardware

This cooler serves routers switches and similar small enclosures that need active airflow within a 25 mm footprint. Builders who require higher static pressure larger dimensions or a different voltage should look at other models.

5 V 0.04 A three-pin power specification

The single deciding specification is the 5 V 0.04 A rating on a three-pin connector. Verify that your board header supplies exactly this voltage and current before purchase.

Questions about this item

How is the 3-pin connector installed on the AD0205LB-D53, and what step is often missed?

Align the three pins with the 5 V header on the router or switch board, press straight down until fully seated, and verify the keyed notch matches; the step often missed is confirming the key orientation before applying force.

What maintenance will the ball-bearing 25x15mm fan need later?

The ball bearing is sealed and rated for continuous operation; no lubrication or bearing service is required, only occasional dust removal from the blades with compressed air.

What limit appears first when the AD0205LB-D53 runs continuously at 5 V 0.04 A?

The motor draws a fixed 0.04 A at 5 V, so the first limit is the thermal ceiling of the ball bearing under sustained load rather than a current or voltage threshold.
