6.8 µF, 6.3 V — molded tantalum for bulk decoupling
The TAJB685K006H is a molded tantalum capacitor from the KYOCERA AVX TAJ series, offering 6.8 µF capacitance at a 6.3 V rated voltage with ±10% tolerance — a common bulk-decoupling value for 3.3 V and 1.8 V rails where the derating margin is adequate. The 1411 (3528 Metric) case with size code B measures 3.50 mm x 2.80 mm, seated height 2.10 mm max — a low-profile footprint that fits dense PCB layouts, though the 2.10 mm height may be tight under a mezzanine board.
