Why Choose the Mersen F094305 High-Speed Miniature Fuse?
The Mersen F094305, catalogue reference MI6FA25V0.05, is a compact high-speed miniature semiconductor fuse designed to protect sensitive semiconductor devices, electronic circuits and industrial control equipment against damaging overcurrents and short circuits. It forms part of Mersen's 6.3 × 32 mm FA semiconductor fuse range, developed for applications requiring extremely rapid fault interruption.
With a rated current of 0.05 A and a rated voltage of 250 V AC, the F094305 provides precise protection for very low-current electronic and instrumentation circuits. Its ultra-fast FA operating characteristic helps limit the electrical and thermal energy reaching delicate components during a fault, reducing the risk of equipment damage.
The fuse is manufactured in a standard 6.3 × 32 mm ceramic cartridge format with ferrule end caps for installation in a compatible clip-mounted fuse holder. Its compact, replaceable construction makes it suitable for industrial controls, test equipment, power supplies and other electronic assemblies where dependable low-current protection is required.
