Littelfuse 441 0603 I²t Fuses are surface-mount devices for circuits requiring high working ambient temperatures (up to 150°C) and high inrush currents. These devices feature excellent temperature stability, performance reliability, and fast response characteristics. The series has high inrush current withstand (I²t) ratings up to 2.6A²S (6A current rating) for eliminating nuisance fuse open during momentary overload conditions. Littelfuse 441 0603 I²t Fuses are designed for use in handheld electronics, LCD displays, battery packs, hard disk drives, and SD memory cards.
