Why Choose the Mersen N208139 High-Speed Fuse?
The Mersen N208139, catalogue number MI6FAP25V0.125, is a compact high-speed miniature fuse with axial leads designed to protect sensitive semiconductor devices and electronic components against damaging overcurrents and short circuits. Its very fast-acting FA characteristic provides rapid fault interruption, helping to limit the electrical and thermal energy reaching protected circuitry.
Rated at 0.125 A and 250 V AC, the N208139 is suitable for low-current electronic circuits, industrial automation equipment and semiconductor applications where conventional general-purpose fuses may not respond quickly enough. Its standard 6.3 × 32 mm miniature cartridge format provides dependable protection within compact electrical assemblies.
The integrated axial leads allow the fuse to be soldered directly onto printed circuit boards or connected to other components without requiring a separate fuse holder. Manufactured as part of Mersen’s semiconductor miniature fuse range, the N208139 offers reliable high-speed protection for OEM equipment, control electronics and power conversion systems.
