Why Choose the Mersen R084103 Semiconductor Miniature Fuse?
The Mersen R084103, catalogue reference MI5SA25V0.5, is a compact semiconductor protection miniature fuse designed to protect sensitive electronic components and control equipment against damaging overcurrents. It forms part of Mersen's 5 × 20 mm SA/SB miniature fuse range for industrial electronics and electrical control applications.
Its SA medium time-lag characteristic allows the fuse to withstand brief current surges while still responding to sustained overloads and short-circuit conditions. This helps reduce unnecessary fuse operation in circuits containing capacitors, transformers, power supplies and semiconductor components that can produce temporary inrush currents during energisation.
With a rated current of 0.5 A and a rated voltage of 250 V AC, the R084103 provides precise protection for low-current electronic circuits. Its standard 5 × 20 mm cartridge format is designed for clip mounting in a compatible miniature fuse holder, allowing straightforward installation and replacement.
