Why Choose the Mersen Q084010 MI5FA25V4 High Speed Miniature Fuse?
The Mersen Q084010, catalogue reference MI5FA25V4, is a compact high speed semiconductor miniature fuse designed to protect sensitive electronic components, measuring equipment and industrial control apparatus against overcurrents and short circuits. It forms part of Mersen's proven MI5 FA/FB miniature fuse range.
Rated at 4 A and 250 V AC, the Q084010 features a very fast-acting FA characteristic. Its rapid response helps restrict the electrical and thermal energy transferred to semiconductor devices during a fault, reducing the risk of component damage and costly equipment downtime.
The fuse uses a standard 5 × 20 mm ceramic cartridge format for installation in a compatible clip-mounted fuse holder. Its compact dimensions, super-fast operating performance and high fault-interruption capability make it suitable for industrial electronics, instrumentation, automation equipment and specialised power-electronic assemblies.

Rapid Protection for Sensitive Electronic Equipment
Semiconductor devices can be damaged by fault currents that persist for only a short period. High speed fuses are engineered to respond much faster than standard general-purpose fuses, helping to minimise the thermal and electrical stress placed on sensitive components.
The Mersen Q084010 combines a very fast FA operating characteristic with a compact ceramic cartridge construction. This makes it suitable for protecting semiconductor devices and measuring or control apparatus where rapid fault clearance, dependable performance and limited installation space are important.
