330 µF, 10 V, 50 mOhm — the D-case workhorse
The TPSD337K010S0050: The 50 mOhm ESR at 100 kHz is the spec that governs ripple handling — for a 1 A ripple current, the self-heating is I²R = 50 mW, well within the 2000-hour endurance budget at 125°C. The D-case (2917 / 7343 Metric) footprint is standard across the TPS family, so a layout designed for a 330 µF/10 V D-case accepts this exact ordering code without a board spin.
Temperature range and endurance
The 2000-hour lifetime at 125°C means the capacitor meets the standard tantalum endurance requirement for most power-supply and decoupling roles. The ±10% tolerance is the standard precision grade for tantalum electrolytics — tight enough for output filtering in DC-DC converters where the voltage ripple budget is a few tens of millivolts.
