0452.375MRL Description

Short technical summary and product information.

The Littelfuse 0452.375MRL is a NANO2 Slo-Blo surface mount fuse rated at 375mA and 125VAC/VDC. It features a slow-blow response time, making it suitable for applications with inrush currents that could nuisance-open a fast-acting fuse. The fuse has a breaking capacity of 50A at rated voltage and a nominal cold resistance of 0.2000 ohms.

 

This fuse is housed in a 2-SMD square end block package measuring 6.10mm x 2.69mm x 2.69mm, designed for surface mount soldering. It operates over a temperature range of -55°C to 125°C. The 0452.375MRL is RoHS compliant and halogen free, and carries UL, CSA, and other agency approvals.

 

Typical applications include notebook PCs, LCD TVs, power supplies, networking equipment, telecom systems, battery charging circuits, and industrial equipment. The slow-blow characteristic provides time-delay protection while accommodating transient surge currents.
