The TPSB336K006R0250: This is a molded tantalum capacitor from the TPS series, rated 33 µF at 6.3 V with ±10% tolerance. The 250 mOhm ESR keeps ripple current handling reasonable for a 33 µF part — expect it to sit on a 3.3 V or 1.8 V rail as bulk decoupling, or as the output cap of a low-voltage LDO or buck converter.
B case size — 1411 (3528 Metric) footprint
Manufacturer size code B, which maps to a 1411 (3528 Metric) case. The footprint is 3.50 mm x 2.80 mm with a seated height of 2.10 mm max — a common tantalum outline that fits a standard reflow profile. Surface-mount, so it goes through the same pick-and-place cycle as the rest of the board.
