EG50050S1-C270-S9A SUNON DC5V 0.38A 4.4CFM CPU Cooling Fan

Description

The SUNON EG50050S1-C270-S9A is a high-performance brushless DC cooling fan featuring a 50 mm x 50 mm x 5 mm form factor and a 3-phase, 4-pole motor design. Operating at a nominal 5 VDC with a current draw of 0.38 A, this unit delivers a rated airflow of 4.4 CFM. The internal mechanism utilizes a lubricated sleeve bearing system designed for a service life of 100,000 hours. Constructed with a SECC steel and thermoplastic PPE housing (UL 94V-0 rated) and Liquid Crystal Polymer (LCP) blades, the fan ensures structural integrity under thermal stress. It incorporates a 4-wire interface supporting PWM (Pulse Width Modulation) for intelligent speed control, typically operating at an auto-regulated 2500 RPM to balance static pressure and acoustic output.
