220 µF bulk decoupling for a 6.3 V rail
The TPSC227K006Y0125: This is a 220 µF molded tantalum capacitor rated at 6.3 V with a 125 mOhm ESR — the three numbers that define its fit on a low-voltage power rail or filter node. The molded case in the 2312 (6032 Metric) footprint is the standard surface-mount package for this capacitance and voltage class — the 6.00 mm x 3.20 mm body and 2.80 mm seated height fit the common decoupling layout near a processor or POL regulator.
