W40S12BMF5-57 Nidec 12VDC 0.68A 40x40x28mm Server Fan

Description

The Nidec W40S12BMF5-57 is a compact 40 mm x 40 mm x 28 mm DC brushless axial fan operating at a nominal 12 VDC and drawing 0.68 A to achieve a maximum rotational speed of 18300 RPM. Engineered with a high-power motor and an optimized wind tunnel design, this unit delivers enhanced pressure characteristics for long-distance wind supply. The internal architecture features a highly durable dual ball bearing mechanism, ensuring extended operational longevity and stable performance under continuous load. Interfacing is facilitated through a standard 4-wire termination, allowing for precise PWM speed control and tachometer signal output, while generating an acoustic noise level of 43 dBA during peak operation.
