What this 68 µF 20 V tantalum capacitor is for
The 2917 (7343 Metric) surface-mount package and size code E fit standard pick-and-place assembly. The 900 mOhm ESR is the figure to budget for ripple current heating — in a 1 A ripple application, the self-heating is roughly 0.9 W, which the molded case must dissipate without exceeding the 125°C ceiling.
