33 µF, 10 V molded tantalum in 1206 case
The TAJA336M010SNJ is a 33 µF, 10 V molded tantalum capacitor from the KYOCERA AVX TAJ series, in a 1206 (3216 Metric) surface-mount case.
ESR and ripple current at 100 kHz
Equivalent series resistance is 1.7 ohm at 100 kHz. For a 33 µF output cap on a 500 kHz buck converter, that ESR contributes roughly 34 mV of ripple at 200 mA load current — acceptable for a 3.3 V rail but marginal for a 1.2 V core supply where ripple tolerance is tighter.
The TAJ series is a broad, long-running line from KYOCERA AVX, so the risk of a sudden EOL is low.
