Overview

Mersen D098121 miniature fuse (SKU: D098121) is a 6.3x32mm, 500V-rated fuse designed for sensitive electronic circuits. Its medium time-lag (SA) characteristic allows short-term surges while protecting semiconductor devices from sustained overcurrent. The fuse’s compact size and clip mounting design make it ideal for space-constrained applications such as power supplies, industrial controls, and instrumentation. With a high breaking capacity, it safely interrupts fault currents up to 500V, ensuring system reliability in harsh environments. The SA time-lag profile balances fast response for critical faults with tolerance for inrush currents common in capacitive loads. Manufactured by Mersen, a leader in electrical protection, this fuse delivers consistent performance across industrial and commercial applications where precision and durability are essential.
