DFS400705PU0T FCN 5VDC 0.5A 40x40x7mm Blower Fan

Description

FCN DFS400705PU0T is a 5VDC 40x40x7mm centrifugal blower fan optimized for high-density thermal management in compact electronics. Engineered specifically as a replacement fan for the HP Thunderbolt Dock 120W G2 (HSN-IXO1), this unit features a highly efficient DC motor and an advanced aerodynamic impeller design to maximize airflow within restricted chassis environments. Utilizing a precision bearing architecture, it ensures low thermal impedance and high structural rigidity during continuous operation. The 4-wire configuration enables precise PWM speed control and tachometer feedback, allowing dynamic acoustic and thermal balancing. Operating at a rated current of 0.5A, this micro-blower delivers exceptional static pressure to overcome high system impedance in docking stations and ultra-small form factor enclosures.
