What this 33 µF tantalum capacitor is and where it sits on the board
The 1206 (3216 Metric) case sits flat on the board — 3.20 mm x 1.60 mm footprint, 1.80 mm seated height — and the molded body gives a consistent profile for pick-and-place.
ESR and temperature range — the fit for your rail
The 1.7 Ohm ESR at 100 kHz sets the ripple current capability — for a 10 V rail with a 100 kHz switching regulator, this capacitor handles the AC ripple without excessive self-heating.
