Description
The NMB 04028DA-12Q-AAF-2, in its two-wire configuration and drawing 0.35A, is a very high-performance 12V DC axial cooling fan from NMB Technologies. It’s perfectly suited for demanding thermal management in compact, high-density electronic systems where space is at a premium. Measuring 40x40x28mm, this fan consumes 4.2W to achieve an impressive 18000 RPM, delivering a strong 20.1 CFM airflow and a significant 1.93 inch-H2O of static pressure to move air against considerable resistance. Equipped with durable ball bearings, it offers a substantial life expectancy of 70,000 hours at 40°C. With its straightforward two-wire connection, it simplifies integration while still providing essential features like auto restart and polarity protection for reliable operation, all at a noise level of 54.5 dBA.
