YY2510M05B SNOWFAN 5VDC 25x25x10mm Axial Fan

Description

SNOWFAN YY2510M05B is a 5VDC 25x25x10mm Axial Fan optimized for precision thermal management in space-constrained micro-electronics. Utilizing advanced Fluid Dynamic Bearing (FDB) architecture, this unit minimizes mechanical friction and thermal impedance, ensuring long-term structural rigidity and silent operation. The aerodynamic PBT impeller is engineered to deliver a concentrated 1.6 CFM airflow while overcoming 4.2 mmH2O static pressure. Integrated 4-wire PWM control allows for dynamic speed scaling from 0 to 9000 RPM, drawing a nominal 0.14A. This micro-fan is specifically designed for high-density integration where low-vibration and intelligent speed modulation are critical for component longevity.
