3.3 µF, 20 V, 4.5 Ohm ESR — bulk decoupling for a 20 V rail
The TAJA335M020RNJ: This is a molded tantalum capacitor from the TAJ series, rated 3.3 µF at 20 V with ±20% tolerance. The 4.5 Ohm ESR sets the ripple-current handling and self-heating — for a 20 V supply bypass, the cap absorbs switching ripple without exceeding its temperature rise limit.
The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm.
