33 µF, 16 V — bulk decoupling for power rails
The TPSY336K016R0300: This capacitance-voltage combination suits it for bulk decoupling on 12 V or 5 V power rails where the 16 V rating provides margin against ripple and start-up transients. The 300 mOhm ESR (equivalent series resistance) governs the capacitor's ripple current capability and self-heating under AC load. For a 100 kHz switching regulator output, this ESR keeps the voltage ripple within a few tens of millivolts at moderate ripple currents — a key parameter for output filter design.
2917 (7343 Metric) — footprint and board integration
This footprint is widely used for tantalum capacitors in power supply outputs and DC-DC converter input/output filtering, and it matches the common Y-size code per EIA-535-BAAC. The molded body offers a flat top for vacuum pickup and consistent solder joint formation.
