The TAJT106K006HNJ: Rated 10 µF ±10% at 6.3 V DC — a standard bulk-decoupling value for 3.3 V and 1.8 V rails, where a 50 % voltage derating (3.15 V applied) keeps the tantalum anode stress well inside the safe operating area. The 4 Ohm ESR at 25 °C sets the ripple-current ceiling and self-heating under AC load — for a 100 kHz switching regulator output, the I²R loss limits the usable ripple to roughly 150 mA RMS before the part exceeds a 10 °C internal rise.
Supplied in a molded 1411 (3528 Metric) case, manufacturer size code T, measuring 3.50 mm x 2.80 mm with a seated height of 1.20 mm max — a low-profile footprint that fits under a 1.5 mm board-to-board clearance.
