Automotive AECQ Ultra-High Inrush 1206 SMD Fuses - 440A Series

Littelfuse's AECQ automotive grade 440A series designed to operate under a wide range of ambient temperatures

Image of Littelfuse's 440A Series SMD FusesLittelfuse's 440A AEC-Q compliant rated surface mount fuse are automotive grade fuses designed to operate under a wide range of ambient temperatures normally associated with automotive environments as low as -55°C up to +150°C with ultra-high inrush current withstand capability to avoid nuisance fuse openings. This Littelfuse 1206 fast-acting fuse ensures excellent temperature stability and performance reliability. The fast response to faulty currents ensures overcurrent protection to sensitive auto-electronics applications.
