Active production — what it means for the BOM line
The SCCY1AB857SLBLE: For a BOM that already carries this order code, it remains a valid design-in choice with no forced migration horizon.
850 F at 2.7 V — energy storage and pulse capability
Rated 850 F at 2.7 V, this cell stores roughly 3.1 kJ (0.86 Wh) at the full rated voltage. The 0.8 mOhm ESR at 1 kHz means the internal voltage drop during a 100 A pulse is under 80 mV — the cell can deliver short-duration current bursts without significant IR drop eating into the usable energy. The 0%, +100% tolerance on capacitance means the actual part may measure anywhere from 850 F up to 1700 F. The ESR is the tighter spec for pulse performance; the wide capacitance tolerance is normal for supercapacitor cells and is factored into the system's energy budget by design.
Chassis-mount weld-stud — mechanical integration
The termination is a weld stud — not a snap-in or screw terminal. The cell mounts to a chassis or busbar via the stud, which is welded to the internal electrode stack. The 35 mm diameter by 117 mm tall radial can requires a panel cutout or bracket; the stud is intended for bolted or welded busbar connection, not a PCB.
Temperature and lifetime derating
Rated lifetime is 1000 hours at 60°C. The operating range is -40°C to 65°C. Below 60°C the lifetime extends significantly per the Arrhenius model typical for carbon-based supercapacitors — at 40°C the expected life is roughly 4× longer, and at 25°C it exceeds 10,000 hours. For outdoor enclosures or engine-bay ambient above 50°C, the 1000-hour rating at 60°C sets the replacement interval.
