Littelfuse Surface Mount Fuse 500mA Slow Blow 125V

Littelfuse Surface Mount Fuse 500mA Slow Blow 125V is a compact surface mount fuse rated at 500mA with a slow blow (time-delay) characteristic, designed to protect electronic circuits from overcurrent conditions.

Overview

Part of the NANO2 OMNI-BLOK range, this fuse is engineered for reliability and precise operation in compact electronic assemblies. Its slow blow characteristic suits circuits that experience temporary inrush currents, such as those found in power supplies, transformers, and motor controls. This helps to prevent nuisance blowing while still providing protection against sustained overcurrent.

Key Features

• Rated for 125V AC and 125V DC, offering versatile use across low-voltage electronic and electrical equipment
• Compact surface mount case size of 9.73 mm x 5.03 mm, helping to save board space in miniaturised devices
• High breaking capacity of 50 A AC for interrupting significant fault currents
• Supplied with a clip or holder for secure installation onto printed circuit boards (PCBs)
• Construction tailored for automated assembly processes, suitable for high-volume manufacturing

Applications

The fuse is intended for consumer, industrial, and telecommunications equipment where overcurrent protection is required on printed circuit boards. The clip or holder supports a stable mechanical connection and reliable electrical contact during installation.
