15 F, 3 V, 40 mOhm — the hold-up energy and the IR drop
The KYOCERA AVX SCCT30E156SRB is a 15 F supercapacitor from the SCC series, rated at 3 V with a maximum ESR of 40 mOhm at 1 kHz. The 40 mOhm ESR is the key spec for pulse-discharge applications: at a 1 A load the internal voltage drop is 40 mV, so the usable energy down to a 2 V cutoff is nearly the full 67.5 J stored. The -10%/+30% tolerance means a fresh part can measure as high as 19.5 F — budget the minimum 13.5 F for worst-case hold-up time calculations.
Through-hole radial can — board-fit and thermal management
The radial can measures 12.5 mm diameter by 32.0 mm seated height, with 5.5 mm lead spacing for standard 0.1-inch pitch prototyping boards or production PCB layouts. The 1000-hour lifetime at 60°C sets the thermal budget: operating at 65°C ambient derates the life below 1000 hours, while staying at 40°C roughly doubles it per the 10°C Arrhenius rule typical for carbon-based supercaps. Bulk packaging means the parts ship loose in a bag or tube — no tape-and-reel for automated pick-and-place.
