35 F, 2.7 V radial supercapacitor — SCC series
The SCCT47B356SRB is a 35 F supercapacitor rated at 2.7 V from KYOCERA AVX's SCC series, packaged in a through-hole radial can with PC pin termination. The 35 F capacitance at 2.7 V stores roughly 127 J of energy — enough to bridge a power gap for a few seconds in a backup or peak-power assist circuit, where the low ESR supports high discharge currents compared to a battery of similar volume. Operating temperature spans -40°C to 65°C, with a rated lifetime of 2000 hours at the upper limit — the electrolyte degradation accelerates above 65°C, so derating the voltage or ambient extends service life in warm enclosures.
Lead spacing is 0.217" (5.50 mm) — this footprint is common among 35 F supercapacitors in this form factor, so the board layout is straightforward. Tolerance of -10% / +30% means the actual capacitance can land between 31.5 F and 45.5 F — the lower bound matters for hold-up time calculations; design the backup duration against the minimum, not the nominal.
