33 µF / 6.3 V — the bulk cap on the rail
The TPSB336K006R0350: 33 µF at 6.3 V with ±10% tolerance — this is the bulk decoupling cap for a 3.3 V or 5 V rail that needs a low-ESR energy reservoir. The 350 mOhm ESR keeps the ripple voltage in check when the load steps; a higher-ESR part would let the rail droop more on a transient.
1411 / 1210 case — what fits on the pad
The package is listed as 1411 (3528 Metric) / 1210 — 3.50 mm x 2.80 mm footprint, 2.10 mm seated height. That is the standard B case size in the TPS series. The pad layout is the same for both designations; a rework tech can confirm the footprint against the board without a microscope.
