2.2 µF, 16 V, 1206 — what this tantalum buys the board
The TAJA225K016HNJ: This is a molded tantalum capacitor from the TAJ series, rated 2.2 µF at 16 V with ±10% tolerance. The 1206 (3216 Metric) case fits standard pick-and-place assembly and reflow profiles. The ESR is 6.5 Ohm at 100 kHz — a typical figure for a small-case tantalum at this capacitance and voltage. Budget this into the ripple-current calculation if the cap sits on a switching regulator output or a DC-DC input filter.
