The 900 mOhm ESR at 100 kHz sets the ripple current handling: on a 5 V supply rail with 100 mV ripple, the cap dissipates about 11 mW — well within the package's thermal budget. The D case (2917 / 7343 metric) footprint is 7.30 x 4.30 mm with a seated height of 3.10 mm. This is the largest case size in the TAJ family, so the board land pattern must match the D-case outline — no substitution with a smaller A, B, or C case without layout change.
It suits avionics power-supply bypass, downhole instrumentation, and satellite payload decoupling where the board sees both cold soak and hot operation. The molded construction with general-purpose features means no conformal-coat requirement at the capacitor level — the board-level coating decision is separate.
The TAJ series is widely second-sourced; if the exact order code is tight, a functionally equivalent D-case 47 µF 25 V tantalum from another manufacturer may fit, but confirm the ESR and temperature range against the design.
