Why Choose the Mersen Z084018 Miniature Semiconductor Fuse?
The Mersen Z084018 is a compact 5 × 20 mm high-speed semiconductor fuse designed to provide rapid protection for sensitive electronic components and semiconductor devices against damaging overcurrent and short-circuit faults. Also identified by catalogue number MI5FA25V0.315, it has a rated current of 0.315 A and a rated voltage of 250 V AC.
Part of the Mersen FA/FB miniature semiconductor fuse series, the Z084018 features a very fast-acting FA characteristic that rapidly interrupts abnormal currents before excessive electrical energy reaches protected semiconductor devices. This helps minimise thermal stress and improves the reliability of electronic equipment, measuring instruments and control circuits.
Manufactured with a ceramic body and ferrule terminals, the fuse is designed for installation in compatible 5 × 20 mm fuse holders. Its compact dimensions and 10 kA breaking capacity make it suitable for industrial automation, instrumentation, electronic control systems and OEM equipment.
