33 µF, 35 V, 900 mOhm ESR — bulk decoupling fit
For a 100 kHz buck output, the ripple voltage across the ESR is the dominant term; a 900 mOhm ESR means the capacitor handles moderate ripple but is not the lowest-impedance choice for a high-frequency rail.
Molded case, 2917 footprint, size code E
Molded construction in the 2917 (7343 Metric) case, size code E — 7.30 mm x 4.30 mm footprint, 4.30 mm seated height. The molded case provides mechanical protection and consistent board-mounting height for pick-and-place.
