Why Choose the Mersen E098122 Medium Time-Lag Semiconductor Fuse?
The Mersen E098122 is a compact medium time-lag semiconductor protection fuse designed to safeguard sensitive electronic components against damaging overcurrents and short circuits. Also identified by the catalogue number MI6SA50V0.25, it combines reliable fault protection with tolerance for brief current surges that occur during normal equipment operation.
With a rated current of 0.25 A and a rated voltage of 500 V AC, the E098122 is suitable for low-current electronic circuits operating at comparatively high voltages. Its SA medium time-lag characteristic allows short-duration inrush and transient currents to pass without unnecessary fuse operation whilst maintaining dependable protection against sustained electrical faults.
The fuse is manufactured in a compact 6.3 × 32 mm cartridge format designed for clip mounting in a compatible fuse holder. Its very high breaking capacity and space-efficient construction make it suitable for industrial controls, instrumentation, power conversion equipment and specialist electronic assemblies.
