Collection: Micro J Case FMM Fuse

Browse our collection of Micro J Case FMM fuses, designed for compact, high-density automotive electrical systems. These space-saving blade fuses are ideal for newer vehicles requiring precise circuit protection in tight spaces. Built with tinned terminals and color-coded bodies by amp rating for easy identification, FMM fuses provide OEM-grade overcurrent protection for critical electronics.

Rated for 32VDC systems with a 1,000A interrupt rating, each fuse operates reliably from -40°C to +125°C. Opening times vary by overload, with precise time-current characteristics for high-performance circuit response. These low-profile micro blade fuses meet the demands of modern automotive electronics while offering direct compatibility with FMM-style holders and blocks.

Perfect for engine compartments, ECU systems, lighting modules, and other space-constrained applications where durability and fast-acting protection are critical.
