Littelfuse PICO II 251 Series Axial Leaded Fuse, 15A Very Fast Acting, 32V

The Littelfuse PICO II 251 Series fuse is a compact, very fast-acting fuse designed for critical circuit protection where a rapid response to overcurrent conditions is essential. With an axial leaded style, it is perfectly suited for PCB (printed circuit board) mounting, providing a reliable and space-saving safety solution for a wide range of electronic and electrical applications.

This fuse offers robust protection with a current rating of 15A and a voltage rating of 32V AC/DC, making it suitable for lower-voltage circuits in power supplies, control modules, and instrumentation. Its defining very fast-acting blow characteristic ensures minimal let-through energy during a fault, helping to prevent damage to sensitive downstream components like semiconductors, integrated circuits, and other valuable electronics.

Constructed to meet high safety standards, it features impressive breaking capacities of 50A AC and 300A DC. This capability allows it to safely interrupt significant fault currents, maintaining system integrity and preventing hazards such as fire or further equipment damage. The compact axial design, measuring just 33mm x 15mm x 43mm, makes it ideal for densely populated circuit boards where space is at a premium.

Key Features & Benefits:

• Very Fast Acting: Provides ultra-quick response to overcurrents, offering superior protection for delicate components.
