5.5 A slow-blow with 50 A breaking capacity at 24 VDC
The 1206SFS550F/24-2: Rated 5.5 A continuous at 24 VDC, this SFS-series fuse interrupts faults up to 50 A without rupturing — adequate for protecting low-voltage DC rails in telecom, instrumentation, or battery-powered equipment where the available fault current stays under that threshold. The slow-blow response (melting I²t of 6.4) lets it ride through the startup inrush of a capacitive input or motor load without nuisance opening — a deliberate choice for circuits with a high surge-to-steady-state ratio.
1206 SMT footprint, -55 to 125°C range
Housed in a standard 1206 (3216 metric) chip package, it reflows with the same profile as passives on the same board — no special handling. The 0.014 Ω cold resistance keeps I²R heating low at full rated current.
