33 µF, 6.3 V, 450 mOhm — what these ratings mean for your rail
The TPSB336K006R0450: The 450 mOhm ESR limits the ripple current handling to roughly 0.5 A RMS at 100 kHz; above that the internal heating raises the case temperature and accelerates wear-out. The 1411 (3528 Metric) / 1210 case footprint is shared across the TPS B-size code, so a pad layout for this cap accepts other B-case tantalums from the same series without a board spin.
Molded epoxy case with a tin-plated termination — standard for reflow soldering. The 3.50 mm x 2.80 mm body and 2.10 mm seated height fit within the profile of a typical 1.6 mm PCB with clearance for conformal coating.
