100 µF, 10 V, 2917 case — bulk decoupling fit
This TAJD107K010SNJ is a 100 µF, 10 V molded tantalum capacitor in the standard 2917 (7343 Metric) case size. For a 1 A step load, the ESR contributes 900 mV of ripple — that is the dominant term in the output ripple budget, so this part suits rails where the transient response spec can tolerate that drop, or where additional output capacitance shares the transient.
The 125°C endurance is the standard tantalum-MnO2 rating; at 85°C the lifetime extends well beyond the 2000-hour figure. Lifecycle status is Active.
Molded case, size code D — board footprint
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm max. The manufacturer size code D means the standard 2917 footprint — the same pad layout used by the T491 series and other common tantalum caps in this case. The molded case provides mechanical protection and a flat top for pick-and-place nozzle contact. The ±10% tolerance is the general-purpose grade — sufficient for bulk decoupling and output filtering where the exact capacitance value is not critical.
