300 F energy reserve for hold-up and power-fail circuits
The KYOCERA AVX SCCY62B307SSB is a 300 F supercapacitor from the SCC series, rated at 2.7 V with a 6 mOhm ESR at 1 kHz. This combination delivers a usable energy storage of roughly 0.3 Wh per cell — enough to sustain a 1 A load for about 80 seconds from a fully charged state, making it a fit for UPS back-up, ride-through, and peak-power assist in industrial electronics. The -10% / +30% tolerance on capacitance means the minimum guaranteed value at end of life is 270 F; the initial charge time and hold-up interval should be budgeted at the low end.
Through-hole solder-lug footprint and thermal limits
Packaged in a radial can with solder lug terminals, the SCCY62B307SSB measures 35 mm in diameter and stands 64 mm seated height. The 0.866-inch (22 mm) lead spacing matches standard PCB hole patterns for large-can electrolytics and supercaps. Operating temperature spans -40°C to 65°C, with a rated lifetime of 1000 hours at 60°C. At 65°C the lifetime derates; for continuous 65°C ambient, expect roughly 500 hours before capacitance drops below the -10% tolerance floor. The 2.7 V rating is the absolute maximum — never exceed it even momentarily, or the cell vents.
Listed as Active by KYOCERA AVX, the SCCY62B307SSB is a current-production part.
