47 µF, 10 V, 1 Ohm ESR — bulk decoupling fit
The TAJB476M010SNJ: This is a molded tantalum capacitor from the TAJ series, rated 47 µF at 10 V with ±20% tolerance and 1 Ohm ESR. The 1 Ohm ESR limits ripple current heating — in a 100 kHz buck converter output filter, the self-heating stays manageable up to roughly 500 mA ripple, but above that the capacitor's internal temperature rise cuts into the 125°C ceiling.
The molded construction and B case code (3.50 mm x 2.80 mm x 2.10 mm) keep the footprint small enough for dense PCB layouts in a sealed enclosure.
