2.2 µF, 10 V — decoupling and filtering fit
The TAJA225K010SNJ: This is a 2.2 µF tantalum capacitor rated at 10 V with ±10% tolerance, housed in a 1206 (3216 Metric) molded case from the TAJ series.
2000-hour endurance at 125°C
The lifetime rating is 2000 hours at 125°C — the maximum rated temperature. In a 85°C ambient, the expected life roughly doubles per the Arrhenius acceleration typical for tantalum capacitors. For a design targeting a 10-year service life at 85°C, this part provides adequate margin for decoupling roles where ripple current is moderate.
