Replacement or spare 40A MIDI fuses with Shoc-Krome high-conductivity plating for maximum current transfer compatible with all Stinger MIDI fuse holders.
The Stinger SPF5840 is a pack of three 40 Amp MIDI-style (Mini ANL) fuses with Shoc-Krome plating. Designed for use with Stinger MIDI fuse holders including the ST5801-S they provide 40A circuit protection with high-conductivity plating to minimise resistance and maximise current transfer at the fuse connection point.

What is a MIDI fuse?
MIDI fuses (also known as Mini ANL) are a blade-style high-current fuse used in automotive power distribution. They are commonly used for amplifier power wiring and branch circuit protection in the 40–200A range.
Are these fuses compatible with the Stinger ST5801-S fuse holder?
Yes. The SPF5840 is compatible with the Stinger ST5801-S and all other Stinger MIDI fuse holders. The 40A rating is a lower-current alternative to the 60A (SPF5860) and 80A (SPF5880) variants in the same range.
When would I use a 40A fuse instead of a higher-rated option?
A 40A fuse is suited to branch circuits or lower-powered amplifiers where the connected wiring and equipment is rated below 40A. Common applications include secondary amplifier feeds on 8 AWG wiring or distribution block branch circuits protecting individual amplifier runs. Always match the fuse to the lowest-rated component in the circuit.
Why does fuse plating matter?
Shoc-Krome plating reduces contact resistance at the fuse terminal, ensuring maximum current transfer between the fuse and holder. Lower resistance means less voltage drop and less heat generation — particularly important in high-current automotive installations.
How many fuses are included in this pack?
The SPF5840 contains 3 MIDI fuses.
