0452012.MRL Description

Short technical summary and product information.

The Littelfuse 0452012.MRL is a NANO2 Slo-Blo surface mount fuse designed for overcurrent protection in compact electronic assemblies. It is rated for 12A continuous current with a voltage rating of 72VAC and 60VDC, and offers a breaking capacity of 50A at rated voltage. The slow blow (time-delay) characteristic allows the fuse to withstand temporary inrush currents without nuisance opening, making it suitable for applications with capacitive or inductive loads.

 

The fuse is housed in a 2-SMD square end block package with dimensions of 6.10mm x 2.69mm x 2.69mm, enabling surface mount assembly. It operates over a wide temperature range of -55°C to 125°C. The nominal cold resistance is 0.0061 ohms, and the melting I²t is 260.46 A²s.

 

This component is RoHS compliant and halogen free, with agency approvals from CSA and UR. It is commonly used in power supplies, networking equipment, LCD displays, battery charging circuits, and industrial controls.
