The TPSC337K006R0080 is a Molded tantalum capacitor from KYOCERA AVX's TPS series, rated 330 µF at 6.3 V with an ESR of 80 mOhm. The 80 mOhm ESR keeps ripple heating low in a 6.3 V rail — for a 1 A ripple current, the internal dissipation is 80 mW, well within the C case's thermal budget at 85 °C ambient.
Housed in the C case (2312 / 6032 Metric), measuring 6.00 mm x 3.20 mm with a seated height of 2.80 mm. The surface-mount footprint matches the standard 6032-28 tantalum pad layout — no via-in-pad or buried via needed for the two-terminal package.
