Why Choose the Mersen Z084202 Miniature Semiconductor Fuse?
The Mersen Z084202 is a compact 6.3 × 32 mm high-speed semiconductor fuse designed to protect sensitive electronic components and power-semiconductor devices against damaging overcurrent and short-circuit faults. Also identified by catalogue number MI6FA50V0.25, it has a rated current of 0.25 A and a rated voltage of 500 V AC.
Part of the Mersen FA miniature semiconductor fuse series, the Z084202 features a very fast-acting characteristic that interrupts abnormal currents before excessive fault energy reaches the protected equipment. This rapid response helps minimise thermal and electrical stress on diodes, thyristors, rectifiers, converters and precision electronic circuits.
The fuse is manufactured with a durable ceramic insulating body and ferrule terminals for installation in compatible clip-mounted fuse holders. Its compact construction, low let-through energy and 200 kA minimum breaking capacity make it suitable for demanding industrial automation, instrumentation, power electronics and OEM applications.
