Automotive-grade molded tantalum — what the AEC-Q200 stamp means on your BOM
The TAJB106K016TNJ: This is a molded tantalum capacitor from the TAJ series, rated 10 µF at 16 V with ±10% tolerance. The AEC-Q200 qualification means it passed the stress tests automotive ICs require — temperature cycling, moisture resistance, mechanical shock — so it belongs on a BOM for engine-bay ECUs, cabin controllers, or sensor modules that see the full -55°C to 125°C range.
The 2.5 Ω ESR at 100 kHz sets the ripple current handling — in a 16 V rail with a few hundred mA of switching ripple, this cap stays within its thermal budget.
Package and footprint — size code B
Size code B matches the 1411 (3528 Metric) / 1210 case: 3.50 mm x 2.80 mm footprint, seated height 2.10 mm max. Surface-mount, supplied on tape and reel.
