The TAJD476K016TNJV: 47 µF at 16 V, ±10% tolerance — this is the standard bulk-decoupling value for 12 V rails in automotive ECUs and infotainment modules. The 16 V rating gives headroom above the nominal 12 V bus; a 10 % derating on voltage is common practice for tantalum to avoid surge failures. ESR is 900 mOhm at 100 kHz — relevant for ripple current handling in switching power supply outputs. The 2917 case dissipates heat through the board copper; keep the ripple current below the derating curve in the datasheet.
Automotive grade and temperature range
AEC-Q200 qualified — the passive-component automotive stress test. This covers temperature cycling, moisture resistance, and mechanical shock. Lifetime rated 2000 hours at 125°C — the accelerated life test condition.
2917 (7343 Metric) case, size code D. Dimensions 7.30 mm x 4.30 mm x 3.10 mm max. This is the most common tantalum case size — compatible with AVX TAJ series and most competitor D-case footprints. The 2917 pad layout is standard; no special via-in-pad or thermal relief required for typical automotive PCB designs.
