The TPSC227M006S0125: This TPS-series molded tantalum delivers 220 µF at 6.3 V with a 125 mOhm ESR, fitting the C-case 2312 (6032 metric) footprint. The 125 mOhm ESR keeps ripple heating manageable on a 3.2 mm wide board — useful for power rail smoothing where a ceramic cap's voltage coefficient would drop capacitance under bias.

Molded package, tape-and-reel delivery
Supplied on Tape & Reel (TR), the molded 2312 case (6.00 mm × 3.20 mm, seated height 2.80 mm max) reflows well under standard lead-free profiles. The ±20 % tolerance is typical for tantalum electrolytics — budget the low-side capacitance in your ripple current calculation.
