The 900 mOhm ESR at 100 kHz is the figure to budget for ripple current: at 1 A ripple the self-heating is 0.9 W, which the 2917 case dissipates through the board copper — the lifetime derating curve starts at that point. ## Temperature grade and field deployment The molded case and ±20% tolerance are standard for general-purpose bulk decoupling; the 4 V rating means it fits 1.8 V and 2.5 V rails with derating, but a 3.3 V rail leaves only 0.7 V headroom — a 6.3 V or 10 V part would be safer for 3.3 V.","metaTitle":"TAJD477M004SNJ KYOCERA AVX 470 µF 4 V Molded Tantalum","metaDescription":"TAJD477M004SNJ from KYOCERA AVX: 470 µF, 4 V, ±20%, 2917 (7343 Metric), 900 mOhm ESR, -55 to 125°C.
