The 900 mOhm ESR sets the ripple current ceiling and the output ripple amplitude — for a 100 kHz, 1 A ripple current, the self-heating is roughly 0.9 W, which must stay within the part's thermal budget at the ambient temperature. ## Active production, full temp range ## Molded case, standard footprint The molded 2917 case (7.30 x 4.30 x 2.00 mm seated height) is a standard tantalum footprint — no special pad geometry required.","metaTitle":"TAJY477M004RNJ Capacitor – KYOCERA AVX TAJ Series, 470 µF","metaDescription":"KYOCERA AVX TAJY477M004RNJ specialty capacitor: 470 µF, 4 V, ±20%, 900 mOhm ESR, -55 to 125 °C, molded 2917 case.
