Why Choose the Mersen Q093279 MI6FA69V0.1 High Speed Miniature Fuse?
The Mersen Q093279, catalogue reference MI6FA69V0.1, is a compact high speed semiconductor miniature fuse designed to provide rapid protection for sensitive electronic components and power-semiconductor devices. It forms part of Mersen's MI6 FA 690 V miniature fuse range, developed for circuits where fast fault interruption and low let-through energy are essential.
Rated at 0.1 A and 690 V AC, the Q093279 features a very fast-acting FA characteristic. This rapid operating performance helps limit the thermal and electrical stress placed on semiconductor components during overcurrent and short-circuit conditions, reducing the risk of costly equipment damage.
The fuse uses a compact 6.3 × 32 mm cylindrical cartridge format designed for clip mounting in a compatible fuse holder. Its very high breaking capacity, low clearing energy and 690 V AC rating make it suitable for converters, diodes, thyristors, triacs, industrial electronics and specialised power-electronic assemblies.

- Semiconductor converter protection.
- Diode protection circuits.
- Thyristor and triac circuits.
- Industrial power electronics.
- Electronic power supplies.
- Automation and control equipment.
- Test and measurement systems.
- OEM electronic assemblies.
