The Littelfuse 015403.5DRT is a board mount fuse from the 154 Series OMNI-BLOK assembly. It is rated for 3.5A at 125VAC/VDC with a slow blow (time-lag) response, making it suitable for circuits that experience inrush currents.
Electrically, the fuse offers a breaking capacity of 50A at rated voltage and a melting I²t of 26.53 A²s. The slow blow characteristic allows temporary overcurrents without nuisance opening, ideal for capacitive loads or motor start-ups.
Mechanically, the fuse is housed in a 2-SMD square end block with holder, measuring 9.73mm x 5.03mm x 3.81mm. The surface mount package with holder enables easy replacement without desoldering. Operating temperature range is -55°C to 125°C. The device is RoHS compliant and Halogen-free, with agency approvals from UL and PSE.
