Active production — where this part sits in the cycle
The TPSY336K016R0400 is flagged as Active on the manufacturer's lifecycle record — no NRND, no last-time-buy, no EOL notice on file. For a shortage-desk buyer, that means the franchised channel still carries it and the independent market is not yet pricing in a discontinuity premium.
33 µF at 16 V — the bulk decoupling fit
33 µF capacitance with a 16 V rating and 400 mOhm ESR puts this squarely in the bulk-decoupling or output-filter role for 3.3 V, 5 V, or even 12 V rails where the ripple current stays modest. The 400 mOhm ESR is the figure that governs ripple heating in a power-supply output — lower ESR means less self-heating for the same ripple current, so this part handles a given AC load cooler than a higher-ESR sibling.
2917 case — footprint and board-fit
That is a standard tantalum footprint — the land pattern is shared across many TPS-series values, so a single PCB pad serves multiple capacitance options without a layout change. Molded construction gives a flat top and consistent standoff, which helps with pick-and-place nozzle vacuum and reflow solder wetting under the terminations.
