The TAJD476K006RNJ: Housed in the 2917 (7343 Metric) molded case, size code D, measuring 7.30 mm x 4.30 mm with a seated height of 3.10 mm. Surface-mount only — the molded body is standard for reflow; the part's thermal mass is moderate, so a standard lead-free profile works.
For a capacitor sitting near a hot regulator or inside an engine-bay ECU, the 125 °C ceiling gives margin above the 105 °C typical of under-hood air. Derate the voltage above 85 °C per the standard tantalum derating curve; at 125 °C the applied voltage should not exceed 2/3 of the 6.3 V rating.
