6.8 µF, 16 V, 2.5 Ohm ESR — bulk decoupling for a 16 V rail
The TAJB685K016YNJ is a molded tantalum capacitor from the TAJ series, rated 6.8 µF at 16 V with a ±10% tolerance.
Molded case, size code B — footprint fits 1411 / 3528 Metric land pattern
The molded case measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max, matching the standard 1411 (3528 Metric) footprint. The size code B designation is consistent across the TAJ series, so the land pattern is shared with other B-size parts in the family.
