For a 100 kHz buck converter output, this ESR contributes about 0.3 W of loss at 0.8 A ripple, which the part can handle without derating. ## Active — no LTB window to manage This cap is suitable for avionics power supplies, satellite bus decoupling, downhole instrumentation, or any environment where the board sees temperature extremes. The 125°C upper limit means the part can sit next to a hot processor or power inductor without forced airflow.","metaTitle":"TAJE477M004RNJ KYOCERA AVX Molded Tantalum Cap 470 µF 4 V","metaDescription":"TAJE477M004RNJ KYOCERA AVX TAJ series molded tantalum capacitor: 470 µF, 4 V, ±20%, 2917 case, 500 mOhm ESR, -55°C to 125°C.
