220 µF, 6.3 V, 70 mOhm ESR — bulk decoupling for tight voltage rails
The TPSC227M006R0070 is a 220 µF molded tantalum capacitor rated at 6.3 V, with a 70 mOhm ESR that sets the ripple current ceiling and self-heating floor for power rail decoupling. The 70 mOhm ESR is the key parameter for a bulk capacitor on a tight voltage rail — it limits the I²R heating at the ripple frequency and determines how much AC current the cap can handle before the internal temperature rise exceeds the derating curve.

The molded case and surface-mount 2312 (6032 Metric) footprint (6.00 mm x 3.20 mm, seated height 2.80 mm) fit standard reflow assembly processes; the ±20% tolerance is typical for tantalum electrolytics and should be factored into the output voltage ripple budget.
