47 µF, 16 V, 200 mOhm — the parametric anchor
The TPSD476K016R0200: The 200 mOhm ESR is the figure that governs ripple current handling and transient response in a power rail — a lower ESR means less self-heating and tighter output regulation under load steps. The ±10% tolerance is the standard production grade for this capacitance and voltage combination.
ESR and the D-case footprint
The 200 mOhm ESR at 100 kHz sets the ripple current capability — for a typical buck converter output, this capacitor can handle the AC ripple without exceeding the internal temperature rise limit. The D-case (7343 metric) footprint is the most common tantalum case size for this capacitance range, making PCB layout and alternate sourcing straightforward. Surface-mount assembly on the 2917 package requires standard reflow profiles; the molded case construction provides mechanical robustness against board flex during assembly and in-service vibration.
Active lifecycle and supply posture
The tape-and-reel packaging option supports automated pick-and-place for volume assembly.
