MERSEN FUSE 250V FA 0,05 A 6.32 MI6FA25V0,05

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.

Ultra-Fast Protection for Sensitive Electronic Circuits

Semiconductor devices and precision electronic components can be damaged by fault currents that develop too quickly for conventional time-delay fuses to interrupt effectively. High-speed fuses such as the Mersen F094305 respond rapidly, helping restrict the energy passed into the protected circuit.

The F094305 combines a very low 50 mA current rating with a compact, replaceable cartridge design. This makes it particularly suitable for instrumentation, control electronics and other applications where precise protection and convenient fuse replacement are important.

Typical Applications

• Semiconductor device protection.
• Precision electronic circuits.
• Industrial automation and control equipment.
• Measurement and instrumentation systems.
• Electronic power supplies.
• Test and laboratory equipment.
• Printed circuit board assemblies with fuse holders.
• Low-current circuits requiring ultra-fast fault interruption.
