Molded tantalum in a 1206 footprint
The TAJA105M016SNJ: This is a molded tantalum capacitor from the TAJ series, built in a standard 1206 (3216 Metric) surface-mount case. The molded construction gives consistent dimensions and a flat top for pick-and-place handling. Rated 1 µF at 16 V with ±20% tolerance, it targets decoupling and filtering roles where the voltage margin and capacitance are moderate.
ESR and lifetime at 125°C
The 11 Ohm ESR at 100 kHz sets the ripple current ceiling — at this impedance, the self-heating from ripple current is manageable for low-power rails but limits use in high-ripple switching supplies without derating. Rated for 2000 hours at 125°C, the capacitor can survive sustained high-temperature operation typical of engine-bay or industrial enclosures, though the actual service life depends on applied voltage and ripple current.
Listed as Active by KYOCERA AVX. The part is suitable for new designs and production builds without last-time-buy pressure.
