Why Choose the Mersen V208260 High-Speed Miniature Fuse?
The Mersen V208260, catalogue number MI5FAP25V2.5, is a compact high-speed miniature fuse designed to protect sensitive semiconductor devices and electronic circuits against damaging overcurrents and short circuits. Manufactured as part of Mersen’s FA/FB semiconductor miniature fuse range, it combines fast operation with a space-saving 5 × 20 mm ceramic body.
This fuse has a rated current of 2.5 A and a maximum rated operating voltage of 250 V AC. Its high-speed FA characteristic provides rapid interruption of fault currents, helping to limit the energy passed to vulnerable electronic components and reduce the risk of equipment damage.
The V208260 is supplied with axial leads, allowing it to be soldered directly onto printed circuit boards or connected within compact electronic assemblies. Its ceramic construction, 10 kA minimum interrupting rating and low I²t values make it suitable for reliable protection in power conversion, industrial electronics and semiconductor-based equipment.

Fast Protection for Sensitive Electronic Components
High-speed fuses are designed to operate more rapidly than standard general-purpose fuses. By interrupting excessive current before damaging thermal energy can build up, the Mersen V208260 helps protect semiconductors, power electronic components and printed circuit board assemblies.
The fuse’s low I²t performance limits the amount of energy allowed through during a fault. Combined with its high interrupting capacity and ceramic construction, this makes the V208260 suitable for electronic equipment where fast and dependable fault isolation is essential.
