For a 4 V rail carrying 1 A ripple at 500 kHz, the power dissipation in the capacitor is I² × ESR ≈ 45 mW, well within the part's thermal budget at 85°C ambient. General-purpose feature class means this part does not carry an extended-reliability or automotive-grade qualification — it is suitable for commercial and industrial equipment where standard tantalum derating rules apply.","metaTitle":"KYOCERA AVX TPSD337K004R0045 Tantalum Cap, 330 µF, 4 V","metaDescription":"Active KYOCERA AVX TPSD337K004R0045 molded tantalum capacitor, 330 µF ±10%, 4 V, 45 mOhm ESR, D-case 2917.
