F-331-1

The F-331-1 from Aearo Technologies LLC, a 3M company pioneers a new class of Fans - Accessories solutions for aerospace thermal control systems. This radiation-hardened component features gallium nitride power electronics capable of operating in 50krad(Si) environments. Its metamaterial heat sink design provides negative thermal expansion characteristics for satellite thermal balancing.Designed as a zero-maintenance Fan Mount, this unit implements magnetic levitation bearings with >100,000 hours MTBF. The atomic layer deposition coating ensures outgassing compliance with NASA-STD-6012 standards.Tailored for Flange Thickness 19 ~ 20mm, Hole Diameter 3.2 ~ 4.4mm applications in space-constrained avionics, this adapter features hermetic sealing that maintains <1x10 atm-cc/sec helium leak rates. The non-outgassing adhesives meet ECSS-Q-ST-70-02C qualification requirements.With a 2.06" (52.3mm) configuration optimized for launch vehicle vibrations, this component survives 40Grms random vibration profiles. The isoelastic mounting system attenuates mechanical shocks by 90% while maintaining thermal contact pressure.
