330 µF bulk tantalum for power-rail smoothing
The TAJE337K010RNJ is a molded tantalum capacitor from the TAJ series, delivering 330 µF at 10 V in a standard 2917 (7343 Metric) case. Tolerance is ±10%, which is tight enough for most filtering and hold-up applications without forcing over-specifying the next stage.
ESR and ripple current — what 900 mOhm means
The 900 mOhm ESR is typical for a standard TAJ-series tantalum at this case size. It limits the RMS ripple current the part can handle before self-heating becomes a concern — for a 10 V rail with moderate ripple, it is adequate; for high-frequency switching regulators, a low-ESR polymer or TPS-series alternative would be a better fit.
This part can be designed into new production runs without worrying about a last-time-buy window.
