LITTELFUSE - SMD Fuse, Slow Blow - 125V 3A

The LITTELFUSE NANO2® Slo-Blo® SMD Fuse is an advanced circuit protection component engineered to prevent nuisance tripping from inrush currents. Its unique time-delay design allows it to withstand initial power surges that would typically blow a fast-acting fuse, offering enhanced reliability for a wide range of electronic devices. This slow blow characteristic is essential for protecting circuits containing capacitive, inductive, or motor loads, where a high momentary current is normal during start-up.

Housed in a compact, industry-standard 2410 case style, this surface-mount fuse is ideal for space-constrained PCB designs. It features a low temperature derating profile, ensuring stable and predictable performance even in demanding thermal environments. With a broad operational temperature range from -55°C to +125°C, it is suitable for both industrial and commercial applications where extreme conditions may be encountered.

The fuse provides reliable protection for sensitive components, with a substantial breaking capacity of 50A for both AC and DC circuits. This makes it a robust safeguard against overcurrent events, helping to prevent damage to downstream electronics. Its SMD format allows for efficient, automated placement during high-volume manufacturing, streamlining production processes.

Designed for integration into power supplies, computer peripherals, telecommunications equipment, and consumer electronics, this component is a critical element in modern circuit design. By selecting a slow-blow fuse from the reputable LITTELFUSE NANO2® series, designers ensure enhanced durability and reduced field failures due to inrush-related issues.
