Capacitor identity and key parametrics
The TPSW226M016R0500: The 500 mOhm ESR (Equivalent Series Resistance) is the dominant loss term in this part — it governs ripple current handling and self-heating under load, so the derating curve matters more than the bare capacitance when the board sees high-frequency ripple from a switching regulator.
Package footprint and board-fit
The molded construction means the capacitor body is a solid epoxy block — no conformal coating issues, but the thermal pad under the part should have adequate copper area to pull heat from the internal anode during high-ripple operation.
