Bulk decoupling at 220 µF — what the ratings decide
The TAJD227M010SNJ: At 220 µF and 10 V rated, this TAJ-series molded tantalum provides the charge reservoir for a rail that sees a load step — the 500 mOhm ESR sets the initial voltage droop before the regulator reacts.
The molded 2917 case handles the thermal expansion mismatch across the solder joint over these extremes.
