Bulk capacitance for low-voltage rails
The TPSC337K004R0100 is a 330 µF tantalum capacitor rated at 4 V, from KYOCERA AVX's TPS series. It comes in a molded case, size code C, with a 2312 (6032 Metric) footprint. The ±10% tolerance covers the full capacitance range at 25 °C and rated voltage. In a 3.3 V rail post-regulator, this ESR keeps the ripple voltage under 10 mV peak-to-peak for ripple currents up to 1 A.
