The TAJB156K004RNJ: The 15 µF capacitance at 4 V rated voltage is a common bulk decoupling value for low-voltage rails.
Package and footprint — size code B
Molded case, size code B, measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The 1411 (3528 Metric) footprint is a standard tantalum capacitor land pattern — no via-in-pad or fine-pitch concerns.
