Why Choose the Mersen X208262 Miniature Semiconductor Fuse?
The Mersen X208262 is a high-speed 5 × 20 mm miniature semiconductor fuse designed to protect sensitive electronic components against damaging overcurrent and short-circuit faults. Identified by catalogue number MI5FAP25V4, it has a rated current of 4 A and a rated voltage of 250 V AC.
Part of the Mersen FA/FB miniature semiconductor fuse series, the X208262 features a very fast-acting characteristic that limits the electrical energy passed into protected components during a fault. This rapid response helps reduce thermal stress on semiconductors, power electronics and precision control circuits.
The X208262 incorporates axial leads for direct soldering onto printed circuit boards or connection within electronic assemblies. Its compact dimensions, ceramic construction and high breaking capacity make it suitable for industrial automation equipment, power supplies, instrumentation and OEM electronics.
