Bulk decoupling on a 10 V rail — what the ratings mean
The TPSD337M010H0100: That ESR figure is the one that governs ripple handling in a switching regulator output — at 100 kHz the impedance is dominated by the ESR, not the capacitive reactance, so the capacitor's self-heating under ripple current is proportional to I² × 100 mOhm. For a 10 V rail feeding a 3 A peak-load step, this part provides enough bulk charge to hold the voltage within a few percent without needing a bank of smaller ceramics.
Temperature range and deployment context
At 125°C the voltage derating applies — the 10 V rating should be derated to roughly two-thirds for reliable operation, so keep the applied DC voltage below 6.7 V if the capacitor sits near its temperature ceiling. The D case (2917) footprint is a standard for high-density SMD tantalum; the 3.10 mm seated height fits under most low-profile enclosures.
