Bulk capacitance with a low-ESR floor
The TPSV477K006R0055: 470 µF at 6.3 V in a molded 2924 case — this is a bulk tantalum for rail decoupling or hold-up storage where the board has the footprint for a large chip. The 55 mOhm ESR is the number that governs ripple current: lower ESR means the cap can absorb more AC ripple before self-heating pushes it past the 125°C ceiling. The ±10% tolerance is standard for this class — tight enough for most filtering and energy-storage roles, but if you need a precise timing cap you are looking at the wrong part.
Active lifecycle — no LTB clock ticking
If your board lives inside a heated enclosure you have margin; if it sits on a hot engine bay you are at the top of the curve and should check the derating.
