Description
The EFB0812HHB-5N74 is a high-performance DC brushless axial fan engineered for dense industrial and server environments requiring a slim 15 mm profile. Operating at a rated 12 VDC with a 0.40 A current draw, this unit delivers a robust 42.37 CFM airflow and 3.42 mmH2O static pressure. It features a dual ball bearing system for a 70,000-hour service life at 40 °C and utilizes a 4-pin PWM interface for precise speed modulation up to 4500 RPM. The flame-retardant UL 94V-0 plastic construction ensures safety in high-heat applications.
