The TPME106M050S0120: The 50 V rating on this 10 µF tantalum gives you headroom on a 12 V or 24 V bus — derating to 80 % (40 V) is standard practice for tantalum reliability, and that still leaves margin above a 24 V rail. The 120 mOhm ESR at 100 kHz sets the ripple current capability: on a 50 kHz buck converter output, the capacitor's self-heating stays within limits if the RMS ripple current is kept below ~1.5 A (derived from the ESR and the maximum power dissipation of the 2917 case). The molded case (EIA size 2917, 7.30 mm x 4.30 mm) is the standard footprint for this capacitance and voltage class; the 4.30 mm seated height fits most mezzanine and board-to-board clearances.
2917 footprint and board fit
The 2917 (7343 Metric) case is the de facto standard for 10 µF to 100 µF tantalum capacitors at 25 V to 50 V. The 7.30 mm x 4.30 mm footprint matches the industry-standard EIA-7343-31 pad layout — no custom land pattern needed. The molded body is compatible with reflow soldering; typical peak reflow temperature for lead-free assembly is 260 °C, well within the capacitor's temperature rating.
