Littelfuse Surface Mount Fuse, 500mA Slow Blow, 125V

The Littelfuse Surface Mount Fuse is a vital electronic safety component designed to protect sensitive circuits from damage caused by overcurrent conditions. As part of the NANO2 OMNI-BLOK range, this fuse is engineered for reliability and precise operation in compact electronic assemblies. Its 500mA rating with a slow-blow (time-delay) characteristic makes it ideal for circuits with temporary inrush currents, such as those found in power supplies, transformers, and motor controls, preventing nuisance blowing while still providing robust protection.

Rated for 125 volts AC and 125 volts DC, this fuse offers versatile application across a wide range of low-voltage electronic and electrical equipment. The compact surface-mount design, with a case size of 9.73mm x 5.03mm, saves valuable board space in modern, miniaturised devices. It is supplied with a clip or holder for secure and straightforward installation onto printed circuit boards (PCBs), ensuring a stable mechanical connection and reliable electrical contact.

With a high breaking capacity of 50A AC, this fuse can safely interrupt significant fault currents, enhancing the overall safety of the end product. Its construction is tailored for automated assembly processes, making it a suitable choice for high-volume manufacturing. This component is an essential part of designing compliant and safe electronic products for consumer, industrial, and telecommunications applications.
