The TAJD336M025RNJ: 33 µF capacitance at 25 V rated voltage puts this TAJ-series tantalum in the output-capacitor slot for a 12 V-to-3.3 V or 5 V regulator — the 25 V rating gives derating margin against the 12 V rail, and the 33 µF value supplies the hold-up charge for a moderate load step. The 900 mOhm ESR is the self-heating term under ripple current — the thermal rise at the board level needs a quick check against the 125 °C ceiling.
D case 2917 — footprint and temperature grade
Surface-mount D case, 7.30 mm × 4.30 mm, seated height 3.10 mm max — the 2917 (7343 Metric) footprint is a standard tantalum outline; the pad layout matches the common D-case land pattern, so a board already routed for a D-case cap takes this part without a layout change.
Lifecycle status is Active — KYOCERA AVX continues production of this molded tantalum; there is no last-time-buy deadline and no forced redesign for a replacement part.
