The ±20% tolerance is standard for tantalum — the actual capacitance at 6.3 V bias will sit near the nominal, but derate the applied voltage to 50 % of rated (3.15 V) for reliable operation per AVX application guidelines. ## 400 mOhm ESR — the thermal ceiling 400 mOhm ESR at 25 °C sets the self-heating under ripple current — for a 470 µF cap on a 500 mA buck output, the I²R loss is about 100 mW, which is manageable in free air but needs attention in a sealed enclosure. ESR rises at low temperature; at -55 °C it can be several times the 25 °C value, so a circuit that must start cold should budget for higher ripple voltage. ## D-case 2917 — standard footprint The 2917 (7343 Metric) D-case measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm max — it matches the common D-case land pattern used across the TAJ series and many competitive tantalum lines.","metaTitle":"TAJD477M006RNJ — KYOCERA AVX 470 µF 6.3 V Molded Tantalum","metaDescription":"TAJD477M006RNJ from KYOCERA AVX: 470 µF, 6.3 V, ±20%, 2917 (7343 Metric), 400 mOhm ESR, -55°C to 125°C.
