Nano 2 Fuses

NANO2® fuses provide overcurrent and short circuit protection in battery chargers, electronic ballast, ac–dc and dc–dc power converters, and telecommunications equipment. Littelfuse makes very fast-acting and time-delayed/Slo-Blo® versions of NANO2 fuses. All the surface mount fuses boast miniature or subminiature square footprints that save space on printed circuit boards.
