0454.500MR Description

Short technical summary and product information.

The Littelfuse 0454.500MR is a NANO2 Slo-Blo surface mount fuse designed for overcurrent protection in a wide range of electronic applications. It is rated for 500mA continuous current at 125VAC and 125VDC, with a time-delay characteristic that accommodates inrush currents to prevent nuisance openings.

 

Key electrical specifications include a melting I²t of 0.24 A²s, a cold resistance of 0.7 Ohm, and an interrupting rating of 50A at 125VAC/VDC and 300A at 32VDC. The fuse operates over a temperature range of -55°C to 125°C, making it suitable for demanding environments.

 

The fuse is housed in a 2-SMD square end block package with dimensions 6.10mm x 2.69mm x 2.69mm, designed for surface mount assembly. It is RoHS3 compliant and halogen free, with UL and CSA agency approvals. Typical applications include notebook PCs, LCD TVs, power supplies, networking equipment, and battery charging circuits.
