Why Choose the Mersen Z208149 Miniature Semiconductor Fuse?
The Mersen Z208149 is a compact 6.3 × 32 mm high-speed semiconductor fuse designed to provide rapid protection for sensitive electronic components and power-semiconductor devices. Also identified by catalogue number MI6FAP25V1.25, it has a rated current of 1.25 A and a rated voltage of 250 V AC.
Part of the Mersen FA miniature semiconductor fuse series, the Z208149 features a very fast-acting characteristic that interrupts abnormal currents before excessive electrical energy reaches protected components. This helps reduce thermal and electrical stress on diodes, thyristors, rectifiers, converters and precision electronic circuits.
The fuse incorporates axial leads for direct soldering onto printed circuit boards or connection within electronic assemblies. Its ceramic body, compact construction and 200 kA minimum interrupting rating make it suitable for industrial automation, power electronics, instrumentation and OEM equipment.
