The Littelfuse 0452005.MRSN is a NANO2 Slo-Blo surface mount fuse designed for overcurrent protection in space-constrained applications. It is rated for 5A continuous current at 125VAC and features a slow blow (time-delay) characteristic to accommodate inrush currents without nuisance opening. The fuse offers a breaking capacity of 50A at 125VAC/VDC and 300A at 32VDC, with a melting I²t of 53.72 A²s and cold resistance of 0.0136 ohms.
This fuse is housed in a 2-SMD square end block package measuring 6.10mm x 2.69mm x 2.69mm, suitable for surface mount assembly. It operates over a wide temperature range of -55°C to 125°C. The device is RoHS3 compliant and halogen free, and carries approvals from CSA, METI, UR, UL Recognized, PSE, CE, and UKCA.
Typical applications include notebook PCs, LCD/PDP TVs, monitors, backlight inverters, portable DVD players, power supplies, networking equipment, servers, cooling fan systems, storage systems, telecom infrastructure, wireless base stations, white goods, game consoles, office automation, battery charging circuits, and industrial equipment.
