6.8 µF, 35 V — the BOM fit check
The TAJD685M035SNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 6.8 µF with ±20% tolerance and a 35 V working voltage. The 1.3 Ohm ESR at 100 kHz sets the ripple current ceiling — for a 35 V rail decoupling a 100 mA load step, the internal temperature rise stays under 10°C, keeping the part within its derated safe operating area.
