Littelfuse 348003 is a small, fast-acting fuse designed for use in sensitive electronic equipment. It is typically used to protect low-voltage DC circuits (up to 24V) from short circuits or overloads. It features a special, soft-acting design that helps absorb electrostatic discharges and has a time-delay characteristic that prevents nuisance tripping due to infrequent, large power surges. The fuse has a voltage rating of 300V and is UL Recognized and CSA Certified.
