5 A, 32 V DC, 50 A breaking capacity — what it means for your board
The Littelfuse 1206SFP500F/32-2 is a 5 A, 32 V DC rated SMD fuse from the SFP series, in a standard 1206 (3216 Metric) package. The 50 A breaking capacity at the rated voltage means it can safely interrupt a short-circuit fault up to that level without rupturing or arcing across the 1206 body — critical for protecting downstream components in a 24 V or 12 V rail. The melting I²t of 5.5 tells you how much energy the fuse absorbs before opening; useful for coordinating with upstream breakers or downstream semiconductor surge ratings.
Obsolete — sourcing through independent channels
Littelfuse lists the 1206SFP500F/32-2 as obsolete.
1206 SMD footprint and temperature range
UL approval means the fuse has passed UL 248-14 testing for branch-circuit protection — a common requirement for safety-certified equipment sold in North America. Tape & Reel packaging is standard for pick-and-place assembly.
