10 F at 3 V — the energy buffer for hold-up and backup
The SCCS30E106SRB: Rated 10 F at 3 V, the part stores about 45 J — enough to ride through a 100 ms power gap at 450 mA draw before the output drops below the downstream regulator's minimum input. ESR is 50 mOhm at 1 kHz — the internal resistance limits the peak discharge current and sets the I²R heating during the pulse; lower ESR means less voltage sag under load.
Temperature and lifetime — the deployment envelope
Operating range -40°C to 65°C with 1000 hours rated life at 60°C — the electrolyte aging accelerates above 65°C; for extended life in a 50°C ambient, derate the charge voltage or expect a shorter service window. Radial can, 10 mm diameter, 32 mm seated height, through-hole PC pins on 5.5 mm lead spacing — the footprint matches standard supercapacitor board layouts; the bulk packaging means reels are not available, so plan for manual or tube-fed insertion.
