470 mF at 5.4 V — energy storage for peak-power bridging
The KYOCERA AVX SCMR14D474PSBB0H is a 470 mF supercapacitor from the SCM series, rated at 5.4 V with a 300 mOhm ESR at 1 kHz. That 5.4 V rating is higher than the common 2.7 V supercap cell, so a single part can sit on a 5 V rail without stacking two in series — saving board space and balancing circuitry. The 0%, +100% tolerance means the actual capacitance can be anywhere from 470 mF up to 940 mF. For hold-up time calculations, budget on the low end; for peak-current delivery, the high end gives extra margin.
Through-hole radial can — rework-friendly footprint
Packaged in a radial can with PC pins and 11.50 mm lead spacing. The through-hole mounting is straightforward to hand-solder or wave-solder, and the part lifts cleanly under hot air if a replacement is needed — no pad damage risk like a large SMD cap. Dimensions are 18.50 mm x 9.50 mm body with a 17.50 mm seated height. The compact footprint fits tight enclosures; the radial leads stand the part upright, minimising board area.
Industrial temp range and endurance
The 1000-hour lifetime at 65°C is the endurance baseline — derate for higher ambient or longer service life.
