4.7 µF, 35 V molded tantalum — TAJ series
KYOCERA AVX TAJC475M035RNJ is a molded tantalum capacitor in the TAJ series, rated 4.7 µF at 35 V with ±20% tolerance. The 2.2 Ohm ESR sets the ripple current ceiling and the filtering corner frequency — for a 4.7 µF cap at 35 V, that ESR is typical of the size C case and means the part handles moderate ripple but isn't a low-ESR choice for high-frequency decoupling.
Case size C — footprint and board fit
Housed in the 2312 (6032 Metric) case, size C per the manufacturer code, measuring 6.00 mm x 3.20 mm with a seated height of 2.80 mm. The 2.2 Ohm ESR at 35 V means the ripple current rating is modest; for a power rail with high AC content, parallel a lower-ESR ceramic to share the ripple.
No pin-compatible direct alternative from the same series is cross-listed — the TAJ series covers a range of capacitance/voltage combos in the same case, but each order code is unique to its rating. Confirm the BOM position count and polarity before committing.
