Why Choose the Mersen K205031 MI5FBP25V0.063 Semiconductor Fuse?
The Mersen K205031, catalogue reference MI5FBP25V0.063, is a compact and highly responsive semiconductor protection fuse designed to safeguard sensitive electronic components against overcurrent and short-circuit faults. Its high-speed FB operating characteristic helps limit fault energy before it can damage semiconductor devices or associated circuitry.
Part of the Mersen 5 × 20 mm FA/FB miniature fuse series, the K205031 combines a very low current rating with a ceramic cartridge construction and axial leads. This configuration enables direct soldering onto printed circuit boards or connection to other components, making it suitable for compact electronic assemblies where conventional clip-mounted fuses may not be practical.
With a rated current of 0.063 A, equivalent to 63 mA, and a rated voltage of 250 V AC, the Mersen K205031 provides precise protection for low-current circuits. Its 4 kA minimum interrupting rating supports dependable fault clearance in suitable industrial and electronic applications.

Fast Protection for PCB-Mounted Electronics
Sensitive semiconductor components can be damaged by fault currents that rise more quickly than conventional protection devices can respond. The Mersen K205031 uses a high-speed FB fuse element to interrupt excessive current rapidly, helping minimise thermal and electrical stress within electronic circuits.
Its axial leads allow the fuse to be soldered directly onto a printed circuit board or connected to other components. This provides a secure installation method for electronic equipment, instrumentation and compact industrial assemblies where reliable low-current protection is essential.
Typical Applications
- Semiconductor device protection.
- Printed circuit board assemblies.
- Industrial electronic equipment.
- Instrumentation and measuring devices.
- Electronic power supplies.
- Automation and control modules.
