Why Choose the Mersen Q208210 High-Speed Miniature Fuse?
The Mersen Q208210, catalogue reference MI6FAP50V2.5, is a compact high-speed semiconductor protection fuse designed to protect sensitive electronic components against damaging overcurrents and short circuits. It forms part of Mersen’s 6.3 × 32 mm FA miniature fuse range, providing rapid fault interruption for industrial electronics and power conversion equipment.
Its very fast-acting operating characteristic helps reduce the thermal and electrical energy passed to semiconductor devices during a fault. This makes the Q208210 particularly suitable for protecting components such as diodes, thyristors, triacs, rectifiers and other electronic devices with limited overcurrent withstand capability.
With a rated current of 2.5 A and a rated voltage of 500 V AC, the fuse provides dependable protection in compact electronic and industrial control circuits. Its axial leads allow direct soldering onto printed circuit boards or connection to other components, helping simplify integration into space-constrained equipment.

Fast Protection for Sensitive Electronic Circuits
Semiconductor devices can be permanently damaged by fault currents lasting only a short period because of their limited thermal capacity. High-speed fuses such as the Mersen Q208210 are engineered to interrupt excessive current rapidly, reducing stress on protected components and helping prevent wider equipment damage.
The compact ceramic body and axial lead configuration make the fuse suitable for integration into printed circuit boards, industrial control modules and power electronic assemblies. Its 500 V AC rating also supports applications operating at higher circuit voltages than conventional miniature electronic fuses.
Typical Applications
- Semiconductor converters and power electronic circuits.
- Protection of diodes, thyristors and triacs.
- Printed circuit boards and electronic assemblies.
- Industrial automation and control equipment.
- Power supplies, rectifiers and converter modules.
- Electronic equipment requiring rapid fault interruption.
