0452.750MRL Description

Short technical summary and product information.

The Littelfuse 0452.750MRL is a member of the NANO2 Slo-Blo fuse series, designed for board-level overcurrent protection in applications requiring time-delay characteristics. This surface mount fuse is rated for 750 mA continuous current and 125 V AC/DC, with a breaking capacity of 50 A at rated voltage.

 

The slow blow (time-delay) response allows the fuse to tolerate temporary inrush currents without nuisance opening, making it suitable for circuits with capacitive or inductive loads. The fuse is housed in a compact 2-SMD square end block package measuring 6.10 mm x 2.69 mm x 2.69 mm, suitable for high-density PCB designs.

 

Key specifications include a melting I²t of 0.904 A²s, operating temperature range of -55°C to 125°C, and CSA and UR agency approvals. The component is RoHS3 compliant and MSL level 1.
