The Littelfuse 0452004.MRL is a NANO2 Slo-Blo fuse designed for surface mount applications requiring inrush current tolerance. This fuse is rated for 4A continuous current at 125V AC/DC with a breaking capacity of 50A. The slow-blow response time accommodates temporary inrush currents, reducing nuisance opening in circuits with capacitive or inductive loads.
Key electrical characteristics include a melting I²t of 34.4 A²s and an operating temperature range of -55°C to 125°C. The fuse is housed in a compact 2-SMD square end block package measuring 6.10mm x 2.69mm x 2.69mm, suitable for high-density PCB designs.
This component carries agency approvals from CSA, PSE, and UR, and is marked RoHS compliant and halogen-free per the manufacturer datasheet. It is part of the 452/454 Series from Littelfuse.
The current rating is 4A.
The voltage rating is 125V and the breaking capacity is 50A.
It is a slow-blow (time-delay) fuse, suitable for circuits with inrush currents.
The package is 2-SMD, Square End Block, with surface mount mounting.
The operating temperature range is -55°C to 125°C.
