Why Choose the Mersen L084420 Medium Time-Lag Semiconductor Fuse?
The Mersen L084420 is a compact medium time-lag semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and control equipment against sustained overcurrent and short-circuit faults. Part of the Mersen MI6SA miniature fuse series, it combines reliable circuit protection with tolerance for brief start-up and switching currents.
Its SA operating characteristic allows the fuse to withstand short-duration current surges that may occur when electronic equipment is energised. This helps reduce unnecessary fuse operation while ensuring that prolonged overloads and potentially damaging electrical faults are interrupted effectively.
With a rated current of 0.2 A, a rated voltage of 250 V AC and a compact 6.3 × 32 mm cylindrical format, the Mersen L084420 is suitable for low-current electronic and industrial control circuits. Its cartridge-style construction enables straightforward installation within a compatible fuse clip or holder.

Reliable Protection with Inrush Current Tolerance
Electronic equipment can draw a temporary surge of current when energised or when internal components switch operating states. The Mersen L084420 uses a medium time-lag characteristic that allows it to tolerate these normal short-duration surges while still responding to sustained overload and short-circuit conditions.
This combination of surge tolerance and dependable fault protection makes the fuse suitable for power supplies, control apparatus, instrumentation and semiconductor-based equipment where nuisance fuse operation could otherwise cause unnecessary downtime.
Typical Applications
- Semiconductor and electronic circuit protection.
- Measuring and control apparatus.
- Industrial electronic equipment.
- Power supply and control circuits.
