BUSSMANN FNQ-1 8 Fuse

FNQ-1/8 is a Bussmann (Eaton Bussmann Electrical Division) midget time-delay fuse designed to protect small circuits from overload and short-circuit conditions. Rated at 0.125 A (1/8 A) and 500 V AC, this non-indicating fuse uses ferrule-end caps and measures 13/32 in by 1-1/2 in, matching standard Bussmann fuse holders. As a time-delay (slow-blow) device, it tolerates brief inrush currents without nuisance tripping, making it suitable for circuits with startup surges such as power supplies, transformers, and control panels. The FNQ-1/8 is part of the FNQ family of cartridge fuses and is typically installed in equipment that requires compact protection in a holder-based assembly. Common applications for FNQ fuses include general purpose circuits, lighting protection, and metering circuits, where reliable protection against overload is needed without immediate interruption on short transients. Endcaps are ferrule-type, ensuring secure electrical contact within compatible Bussmann holders. This specific 1/8 amp variant is widely stocked by distributors and is compatible with standard FNQ fuse holders designed for midget fuses in 13/32 x 1-1/2 inch form factors.
