The TAJD107K010RNJV: That endurance figure is the practical ceiling for a power-rail bulk cap near a hot regulator or a decoupling cap on a DC-DC converter — beyond 2000 hours at 125°C ambient, the leakage current drifts and the cap should be considered consumed.
900 mOhm ESR — what it means for ripple
In a buck converter, a 100 µF tantalum with this ESR contributes ripple per amp of inductor ripple current — manageable for higher-voltage rails but marginal for low-voltage core supplies where the ripple budget is tighter.
The TAJ series is a standard molded tantalum line with broad distribution coverage; lead time is confirmed per RFQ through independent sourcing channels.
2917 footprint — D-size case
The 7.30 mm x 4.30 mm x 3.10 mm (L x W x H) 2917 (7343 Metric) case is the standard D-size tantalum footprint. It mates with the common 2917 land pattern — no via-in-pad, no thermal pad. The molded body is non-hermetic, so a conformal coat over the assembly is recommended if the board sees condensation or washdown.
