Bulk decoupling fit — 22 µF at 20 V in a 2917 footprint
This TAJD226K020SNJ is a 22 µF tantalum capacitor rated at 20 V with a 900 mOhm ESR, housed in the standard 2917 (7343 Metric) D case. The ±10% tolerance keeps the capacitance window tight enough for most power-rail decoupling and hold-up circuits without overspecifying.
That means no last-time-buy scramble — you can spec it into a BOM without planning a substitution for the next two years. Supplied in Tape & Reel (Cut Tape also available), so it loads straight into a feeder for high-speed pick-and-place without a packaging change.
What the 900 mOhm ESR means for your rail
The 900 mOhm ESR is the series resistance at 100 kHz typical for a D-case tantalum at this capacitance-voltage point. Compared to a lower-ESR polymer or MLCC alternative, this tantalum trades some ripple performance for higher capacitance stability under DC bias and better surge robustness in low-impedance circuits.
