F-344-1

Aearo Technologies LLC, a 3M company's F-344-1 establishes new standards in Fans - Accessories innovation for automotive electronics cooling. This ruggedized component meets AEC-Q200 qualification requirements, delivering reliable performance across -40 C to 125 C temperature ranges. Its graphene-enhanced composite material provides exceptional heat dissipation with minimal weight penalty.As a multi-functional Fan Mount, this solution integrates temperature-compensating elastomers that maintain seal integrity across thermal cycles. The stainless steel reinforcement rings prevent creep deformation in high-G vibration environments.Designed for Flange Thickness 2.5 ~ 3.5mm, Hole Diameter 4.2 ~ 5.4mm applications, this adapter features conductive cooling fins that lower junction temperatures by 15 C in compact power supply units. The captive hardware design prevents loose parts in automotive assembly lines.The 0.543" (13.79mm) specification has been optimized through finite element analysis to withstand 50G mechanical shock pulses. The proprietary surface texturing reduces airflow separation by 22% compared to smooth finishes.
