Frequently Asked Questions
What is the current rating and blow characteristic of the Littelfuse 045101.5MRL fuse?
The 045101.5MRL is rated at 1.5 A with a very fast-blow characteristic, meaning it interrupts overcurrent conditions rapidly to protect sensitive downstream components. This fast response time, typically under 1 ms at 200% rated current, makes it well suited for circuits with low-tolerance semiconductors and precision analog stages.
What are the physical dimensions of the 045101.5MRL NANO2 package and how does it fit on a PCB?
The 045101.5MRL measures 6.1 mm in length and 2.69 mm in both width and height, conforming to the standard NANO2 surface mount footprint. This compact body occupies less than 45 mm² of board area, enabling direct integration into tight PCB layouts for USB protection, battery circuits, or handheld device power paths.
In which application types is the 045101.5MRL recommended over a slow-blow fuse?
The very fast-blow 045101.5MRL is recommended when protecting circuits with sensitive ICs, MOSFETs, or diodes that can be damaged by sustained overcurrent within a few milliseconds. Applications such as USB power ports, LED driver outputs, and 1.5 A-class sensor power rails benefit from its rapid 1.5 A interruption threshold compared to slow-blow fuses that allow longer surge durations.
