1 F, 3 V, 240 mOhm — the energy buffer for brief power gaps
The KYOCERA AVX SCCQ12E105PRB is a 1 F supercapacitor rated at 3 V with a maximum ESR of 240 mOhm at 1 kHz. This combination of capacitance and low series resistance makes it suitable for applications requiring a short-duration energy reserve — think real-time-clock backup, power-fail hold-up in metering or industrial controls, or peak-current assist in battery-powered devices where the primary cell cannot deliver the transient load alone. The 3 V rating is the nominal operating voltage; staying within it is the primary constraint for cycle life. The SCC series is a standard through-hole radial-can supercapacitor line from KYOCERA AVX, built for general-purpose energy storage where the load profile involves frequent charge-discharge cycles at moderate currents.
Through-hole radial can — board-fit and thermal notes
This is a standard footprint — the 2.30 mm lead pitch matches many through-hole supercapacitor layouts, and the 6.30 mm can diameter means it fits into a compact board area without crowding adjacent components. The operating temperature range is -40°C to 65°C, with a rated lifetime of 1000 hours at 60°C. For designs that see sustained temperatures near the upper limit, the 1000-hour figure sets the practical replacement interval — or the derating needed if the ambient stays below 60°C. The tolerance is 0%, +100%, meaning the actual capacitance can be anywhere from 1 F to 2 F at delivery; this wide spread is typical for supercapacitors and must be accounted for in timing or hold-up calculations.
