100 µF, 10 V, D-case — what the ratings mean on the board
The TAJD107M010SNJ: This is a molded tantalum capacitor from the TAJ series, 100 µF ±20% at 10 V, in the 2917 (7343 Metric) D-case. The 900 mOhm ESR at 100 kHz sets the ripple current ceiling in a DC-DC output filter — at 10 V you get about 1.1 A ripple current before self-heating cuts into the 2000-hour life at 125°C.
Active — no LTB clock ticking
Listed as Active on the manufacturer's lifecycle.
D-case footprint, tape-and-reel delivery
2917 (7343 Metric) case, 7.30 mm x 4.30 mm footprint, 3.10 mm seated height. The molded body has no polarity mark ambiguity — the anode band is clearly printed on the top.
