220 µF, 10 V, 70 mOhm — the bulk decap for a 10 V rail
The TPSE227K010R0070: That ESR is the number that matters for ripple current handling — the lower the ESR, the more AC ripple the cap can absorb without overheating. For a point-of-load converter switching at 500 kHz, 70 mOhm keeps the self-heating well within the 125 °C ceiling. The 10 V rating means you want to derate to 7-8 V for reliable operation — standard practice for tantalum caps to avoid surge failures. At 220 µF it is sized for bulk decoupling on a 10 V rail, not for high-frequency bypass.
Active production — no last-time-buy to chase
The TPS series is a standard low-ESR tantalum line from KYOCERA AVX. The molded case is the usual epoxy encapsulation — nothing exotic, no conformal-coat gotchas for rework.
2917 footprint — easy swap on site
The 2917 (7343 Metric) package is a common tantalum footprint. That is a standard part — you can pull one from a field kit and swap it with a soldering iron, no hot-air station required. Polarity marking is clear on the molded case. Operating range from -55 °C to 125 °C covers the full industrial band. No derating needed for most environments — the cap is rated for the same temperature range as the rest of the board.
