470 mF hold-up for 5.5 V rails
The KYOCERA AVX SCMR14F474PRBA0 is a 470 mF supercapacitor from the SCM series, rated at 5.5 V with a 380 mOhm ESR at 1 kHz. That capacitance and voltage combination stores about 7.1 J — enough to ride through a 100 ms power glitch on a 3.3 V logic rail drawing 50 mA, or to back up an RTC and SRAM for minutes during a battery swap. The 0%, +100% tolerance means the actual capacitance can land anywhere from 470 mF to 940 mF off the reel. Design the hold-up time budget against the 470 mF floor — the extra headroom on the high side is a bonus, not something to count on for timing.
Through-hole radial can — field-swap friendly
The through-hole mount means you can swap it on site with a soldering iron and a desoldering pump — no hot-air station needed. Polarity is marked on the can; the longer lead is positive, same as an electrolytic. Operating temperature spans -40°C to 65°C, with a rated lifetime of 1000 hours at 65°C. That endurance drops fast above 65°C — if the cap sits near a hot regulator or in an enclosure that hits 70°C, derate the expected life by roughly half for every 10°C rise above the rating.
Active production — no obsolescence watch needed
Listed as Active by KYOCERA AVX with no NRND or EOL flag. The SCM series is a standard catalog line, so the part is in regular production and available through distribution. Supplied in Bulk packaging, which means tubes or loose trays — not tape-and-reel. For a through-hole part used in low-to-medium volume production or prototyping, Bulk is the expected format; no reel fee or minimum reel quantity to worry about.
