MERSEN FUSE 250V FA 0,125 A 5.20 MI5FA25V0,125

Why Choose the Mersen L084029 High Speed Semiconductor Fuse?

The Mersen L084029 is a compact high speed semiconductor fuse designed to provide rapid protection for sensitive electronic components, semiconductor devices and measuring or control equipment. Part of the Mersen MI5FA miniature fuse series, it uses a very fast-acting operating characteristic to interrupt overcurrent and short-circuit faults before excessive thermal energy can damage protected components.

This miniature fuse combines reliable fault protection with a space-saving cylindrical design suitable for electronic assemblies, industrial control equipment and power conversion systems. Its very high breaking capacity helps provide dependable protection in applications where conventional general-purpose fuses may not respond quickly enough.

With a rated current of 0.125 A, a rated voltage of 250 V AC and a compact 5 × 20 mm format, the Mersen L084029 is ideal for low-current electronic circuits. Its clip-mounted construction allows straightforward installation in compatible fuse holders and clips.
