Mersen N205034 MI5FCP25V0.25 fast-acting 5 x 20 mm miniature cartridge fuse with axial leads, rated at 0.25 A and 250 V for semiconductor and electronic circuit protection.
£1.49
The Mersen N205034, catalogue number MI5FCP25V0.25, is a compact fast-acting miniature cartridge fuse with axial leads designed to protect sensitive semiconductor devices and electronic circuits against damaging overcurrents and short circuits. Its FC operating characteristic provides rapid fault interruption, helping to reduce the electrical and thermal energy reaching protected components.
Rated at 0.25 A and 250 V, the N205034 is suitable for low-current electronic assemblies, industrial control equipment and printed circuit boards. Its standard 5 × 20 mm cartridge format provides a compact protection solution for applications where available installation space is limited.
The integrated axial leads allow the fuse to be soldered directly onto printed circuit boards or connected within electronic assemblies. As part of Mersen’s semiconductor miniature fuse range, the N205034 combines straightforward installation with dependable fast-acting circuit protection.
Semiconductor devices and electronic components can be damaged by overcurrent events that develop too quickly for slower general-purpose fuses to interrupt effectively. The Mersen N205034 uses a fast-acting FC characteristic to disconnect fault currents rapidly and help minimise stress on protected circuitry.
Its axial leads allow the fuse to be integrated directly into printed circuit boards, reducing the need for a separate fuse holder. This makes the N205034 particularly suitable for compact OEM assemblies, electronic control modules and equipment requiring a permanent soldered fuse connection.
