Why Choose the Mersen W206030 Fast-Acting Miniature Fuse?
The Mersen W206030, catalogue number MI5FC25V0.31, is a compact fast-acting semiconductor miniature fuse designed to protect sensitive electronic components and semiconductor devices against damaging overcurrents and short circuits. As part of Mersen's 5 × 20 mm FC 250 V miniature fuse range, it provides rapid fault interruption for precision electronic and industrial control applications.
With a rated current of 0.315 A and a rated operating voltage of 250 V AC, the W206030 is suitable for low-current circuits where fast response and controlled let-through energy are essential. Its FC characteristic helps reduce the electrical and thermal stress placed on semiconductor devices during abnormal operating conditions.
The fuse features a durable 5 × 20 mm ceramic cartridge body with ferrule terminals for clip mounting in compatible fuse holders. A 1.5 kA minimum interrupting rating, low melting I²t and low clearing I²t provide reliable protection for industrial electronics, instrumentation, control modules and power supply circuits.
