220 µF at 4 V with 40 mOhm ESR — bulk decoupling for low-voltage rails
The TPSY227M004R0040: The 40 mOhm ESR keeps ripple heating low in power-supply decoupling — a 1 A ripple current dissipates 40 mW, well within the package's thermal budget.
Package and board-fit — 2917 (7343 Metric) footprint
Surface-mount assembly; the molded body suits reflow soldering with typical peak profiles up to 260°C. Tape-and-reel packaging (TR) supports automated pick-and-place. Manufacturer size code Y maps to the 2917 case — useful when cross-referencing to other AVX tantalum series.
