2.2 µF, 16 V, 6.5 Ohm ESR — derating and ripple budget
The TAJA225M016RNJ: Rated at 2.2 µF and 16 V with a ±20% tolerance, this molded tantalum in the TAJ series carries a 6.5 Ohm ESR.
At the high end, the leakage current doubles every 10°C above 25°C — budget for increased DC bias current at 125°C.
1206 case — footprint and layout fit
Housed in a 1206 (3216 Metric) molded case measuring 3.20 mm x 1.60 mm with a seated height of 1.80 mm. The manufacturer size code is A. The 1206 footprint is a standard reflow-friendly size; the molded body provides mechanical stability against board flex during assembly.
