LITTELFUSE Nano2 449 Series SMD Fuse, Slow Blow, 2A, 125V, 2410 Case

The LITTELFUSE Nano2 449 Series SMD Fuse is a compact and reliable slow-blow fuse, engineered for surface-mount applications where board space is at a premium. Designed to offer robust protection against overcurrent conditions, its 2A rating and 125V AC/DC voltage capacity make it an essential safety component in a wide range of low-voltage electronic circuits.

Housed in a compact 2410 case style (6.1mm x 2.5mm metric), this fuse provides a high breaking capacity of 50A, ensuring it can safely interrupt significant fault currents without sustaining damage. The 'slow-blow' or time-delay characteristic is critical, as it allows temporary, harmless current surges (such as those from motor start-up or capacitor inrush) to pass without operating, while still providing reliable protection against sustained overloads and short circuits.

Applications & Key Benefits

This fuse is ideal for integration into power supplies, battery management systems, consumer electronics, and industrial control boards. Its surface-mount design facilitates automated assembly processes, improving manufacturing efficiency and consistency. The product's reliable performance helps prevent costly damage to sensitive downstream components like microcontrollers, sensors, and integrated circuits.
