£2.61
The Mersen Q208256, catalogue reference MI5FAP25V1, is a compact high-speed semiconductor protection fuse designed to provide rapid protection against overcurrents and short circuits in sensitive electronic equipment. Part of Mersen's proven 5 × 20 mm FA miniature fuse range, it offers dependable protection for semiconductor devices and precision electronic circuits.
Its very fast-acting characteristic helps minimise the thermal and electrical energy delivered to protected components during fault conditions. This makes the fuse particularly suitable for safeguarding diodes, thyristors, transistors, rectifiers, power supplies and other semiconductor devices that require rapid fault interruption.
With a rated current of 1 A and a 250 V AC voltage rating, the Q208256 is well suited to industrial electronics, instrumentation and PCB assemblies. The integrated axial leads allow direct soldering to printed circuit boards or convenient installation within compact electronic equipment.
Fast-acting semiconductor fuses are specifically designed to interrupt fault currents before excessive heat can damage sensitive electronic components. The Mersen Q208256 helps improve equipment reliability by limiting fault energy and protecting valuable semiconductor devices from catastrophic failure.
Its compact 5 × 20 mm format and axial lead construction make it suitable for direct PCB installation and use within industrial controls, instrumentation and electronic power systems where dependable overcurrent protection is essential.
