68 µF, 16 V, 100 mOhm ESR — the parametric fit for bulk decoupling
The TPSD686K016R0100: The 68 µF capacitance at 16 V rated voltage with 100 mOhm ESR places this part in the standard bulk-decoupling class for 12 V and 5 V rails where the ripple current stays under 1.5 A RMS. The ESR figure directly sets the self-heating under ripple — a 100 mOhm ESR at 1 A RMS dissipates 100 mW, well within the D-case thermal budget at 85°C ambient. The ±10% tolerance covers the full temperature range from -55°C to 125°C, so the capacitance at the low-temperature end stays above 61 µF — enough margin for hold-up time calculations in cold-start scenarios.
Active lifecycle — no last-time-buy pressure
The TPS series is a long-running molded tantalum platform with broad market adoption. Package and ratings are stable — no recent PCN activity that would affect the 2917 D-case footprint or the 16 V rating.
