Why Choose the Mersen Q076466 MI6FA100V0.63 High Speed Miniature Fuse?
The Mersen Q076466, catalogue reference MI6FA100V0.63, is a compact high speed semiconductor fuse designed to protect sensitive electronic components against overcurrents and short circuits. Its very fast-acting performance helps limit damaging fault energy before it reaches valuable semiconductor devices.
Rated at 0.63 A and 1000 V AC, this miniature fuse is suitable for high-voltage electronic and industrial circuits where rapid fault interruption is essential. It uses a compact 6.3 × 46 mm cylindrical format for installation in a compatible clip-mounted fuse holder.
The Q076466 forms part of Mersen's MI6 FA miniature semiconductor fuse range. Its high breaking capacity, compact dimensions and rapid operating characteristic make it particularly suitable for protecting converters, diodes, thyristors, triacs and other power-electronic components.

Reliable Protection for Power Electronics
Semiconductor devices can be damaged by relatively short-duration overcurrent events. High speed fuses are engineered to interrupt these faults rapidly, reducing the amount of thermal and electrical energy passed through the protected circuit.
The Mersen Q076466 is designed for circuits where conventional general-purpose fuses may not operate quickly enough. Its FA characteristic supports reliable protection of power-electronic components while its 1000 V AC rating makes it suitable for demanding industrial systems.
Typical Applications
- Semiconductor power converters.
- Diode protection circuits.
- Thyristor and triac circuits.
- Industrial power electronics.
- Electronic power supplies.
- Automation and control equipment.
- Test and measurement systems.
- OEM electronic assemblies.
