15 µF at 50 V with 250 mOhm ESR — the parametric triangle
The TPSV156M050R0250: That ESR figure is the one that governs ripple current handling in a bulk decoupling or output filter role — lower ESR means less self-heating and better high-frequency bypass. The molded case (type: Molded) is standard for surface-mount reflow assembly and provides mechanical stability across that range.
V case code — 2924 footprint for layout
That footprint is large enough to keep the ESR low at 250 mOhm while fitting standard pick-and-place equipment. Tolerance is ±20% — typical for tantalum electrolytics. Budget the full spread in your derating calculation; the 50 V rating gives headroom for a 24 V or 28 V rail, but tantalum caps are sensitive to voltage derating below 50% of rated voltage for reliability.
