Compact 40 mm axial fan

The Delta AFB0405LDSize is a 40 x 40 x 20 mm axial fan designed for tight spaces that need forced-air cooling. It runs on 5 V and draws 0.21 A, making it suitable for embedded boards, small-form-factor cases and industrial enclosures.

Integration requirements

The fan needs a 5 V header or regulated supply capable of 1.05 W and accepts standard two-wire or three-wire connectors. Its 20 mm depth leaves room for dense layouts, while the double-ball bearing supports any mounting orientation without extra brackets.

Capacity and limits

At 5500 RPM the fan produces 26 dBA and moves air across a -20 to 75 °C operating range. Rated service life is 60 000 hours at rated voltage. It cannot meet cooling loads that demand higher static pressure or airflow beyond the 35 000 m³/h class.
