100 µF, 10 V, 900 mOhm ESR — bulk decoupling fit
The 900 mOhm ESR is the figure that governs ripple current rating and self-heating — at 100 kHz the capacitor's impedance is dominated by this resistance, so derate the ripple current if the ambient temperature pushes above 85°C.
The molded case and surface-mount 2917 footprint keep the part stable across thermal cycling.
2917 case — standard footprint, broad compatibility
The 2917 (7343 Metric) case size is a de facto standard for tantalum chip capacitors — 7.30 mm x 4.30 mm, seated height 1.50 mm max. This footprint matches industry-wide second-source options, so a BOM position using this code can be cross-referenced against other TAJ-series or equivalent molded tantalum parts without a board layout change.
