Why Choose the Mersen Y079026 Semiconductor Miniature Fuse?

The Mersen Y079026 is a compact, fast-acting semiconductor miniature fuse designed to protect sensitive electronic components and semiconductor devices against damaging overcurrents and short circuits. As part of Mersen's HA 37 semiconductor fuse series, it provides rapid fault interruption for applications where limiting electrical and thermal stress is essential.

The Y079026 features a fast operating characteristic that responds quickly to abnormal current conditions. This makes it particularly suitable for electronic circuits containing vulnerable semiconductor components that may be damaged by fault energy before a conventional general-purpose fuse operates.

With a rated current of 0.31 A, a rated voltage of 250 V AC and a compact 6.3 × 32 mm cylindrical format, the Mersen Y079026 offers reliable protection for industrial electronics, control systems, power conversion equipment and OEM assemblies. Its clip-mounted construction enables straightforward installation in compatible fuse holders.

Key Advantages

  • Fast-acting protection for sensitive semiconductor devices and electronic components.
  • 0.31 A current rating for low-current protection applications.
  • 250 V AC voltage rating for compatible electronic circuits.
  • High breaking capacity helps interrupt damaging fault currents safely.
  • Compact 6.3 × 32 mm cylindrical construction.
  • Clip mounting enables convenient installation and replacement.

Key Features

  • Mersen HA 37 semiconductor miniature fuse series.
  • 0.31 A rated current.
