The 100 mOhm ESR (Equivalent Series Resistance) directly governs ripple current capability and self-heating in the circuit — lower ESR means the part can handle higher AC ripple without exceeding its internal temperature rise. ## ESR and voltage derating — the real selection parameters The 100 mOhm ESR at 100 kHz typical sets the ripple current rating: for a given ripple current I, the internal power dissipation is I² × ESR. A 2 A ripple dissipates 0.4 W in the capacitor body, which must stay within the package thermal limits at the 125°C upper boundary. Designers targeting high-efficiency DC-DC converters with fast switching edges should verify the ripple current against the capacitor's thermal budget. At 6.3 V rated voltage, standard tantalum derating practice recommends operating at no more than 50-60% of rated voltage for reliability, i.e., 3.15-3.8 V DC bias. This is not a KYOCERA AVX requirement but a well-known application rule for solid tantalum capacitors to prevent field failures due to surge current or reverse bias.","metaTitle":"KYOCERA AVX TPSD477K006R0100 Tantalum Cap, 470 µF, 6.3 V","metaDescription":"KYOCERA AVX TPSD477K006R0100 tantalum capacitor, 470 µF, 6.3 V, 100 mOhm ESR, D-case 2917, -55°C to 125°C.
