Bulk capacitance for a 6.3 V rail — what the ratings mean
The 900 mOhm ESR at 100 kHz sets the ripple-current ceiling — for a 6.3 V rail carrying 1 A ripple, the I²R loss is 0.9 W, which heats the part above ambient.
Package and footprint — 2917 (7343 Metric), size code E
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 4.30 mm max. The size code E footprint matches the standard tantalum pad layout for this case — the anode (+) pad is marked on the package body. Surface-mount reflow follows the standard tantalum profile; the molded body is not moisture-sensitive like some polymer caps, but the reels should be stored dry to avoid oxidation on the terminations.
