F-251-1

The F-251-1 by Aearo Technologies LLC, a 3M company redefines Fans - Accessories efficiency with its groundbreaking electromagnetic compatibility design. This cutting-edge component employs frequency-adaptive shielding technology that surpasses CISPR 32 Class B emissions standards. Its multi-layer construction provides 360 protection against both radiated and conducted interference in sensitive RF environments.Functioning as a high-reliability Fan Mount, this solution incorporates strain-relief cable management that reduces wire fatigue by 70%. The ceramic-impregnated polymer housing demonstrates superior arc resistance at altitudes up to 5000m.Optimized for Flange Thickness 9 ~ 10mm, Hole Diameter 2.5 ~ 3.7mm configurations, this adapter implements smart torque-limiting features that prevent overtightening damage. The beryllium-copper contact springs maintain <10m resistance after 50,000 thermal cycles.Precision-machined to 1.38" (35.0mm) specifications, this component achieves VDI 2230 bolt preload accuracy for vibration-proof installations. The micro-channel cooling architecture enables 25% higher heat flux density than conventional designs.
