Frequently asked questions
What is a MIDI fuse?
MIDI fuses, also referred to as Mini ANL fuses, are a mid-format automotive fuse used for circuit protection in car audio amplifier power runs and automotive accessory wiring. They use a different holder format from MAXI blade fuses, ANL fuses, and AGU glass tube fuses and are not interchangeable with those formats. Confirm your fuse holder accepts MIDI fuses before ordering.
How does the SPF5840 compare to other MIDI fuses in the Stinger range?
The SPF5840 is rated at 40 amps, making it the lowest rated MIDI fuse in the Stinger MIDI range reviewed in this session. Higher rated options include the SPF58100 at 100 amps and the SPF58150 at 150 amps. Select the amperage rating appropriate for the circuit being protected based on the current draw of the connected amplifier or accessory and the gauge of cable used in the installation.
Can I replace a blown fuse with a higher amperage rating?
No. Never install a fuse rated higher than specified for the circuit. An oversized fuse defeats overcurrent protection and the wiring or component may overheat before the fuse blows, creating a fire risk. If a fuse blows repeatedly, diagnose and correct the underlying fault rather than increasing the fuse rating.
How many fuses are included in this pack?
The SPF5840 contains three 40 amp MIDI fuses.
Is the SPF5840 compatible with all MIDI fuse holders?
The SPF5840 is a standard MIDI format fuse compatible with all standard MIDI fuse holders. Confirm your fuse holder accepts MIDI fuses before ordering.
