150 µF, 16 V tantalum for bulk storage and filtering
The TAJD157K016RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 150 µF and 16 V with ±10% tolerance — a common bulk capacitance value for 12 V rail decoupling, output smoothing in DC-DC converters, and hold-up storage in power supplies.
Package and footprint check
Housed in the 2917 (7343 Metric) case with dimensions 7.30 mm x 4.30 mm and a seated height of 3.10 mm max — the D size code matches the standard 2917 land pattern, so a PCB already laid out for this footprint accepts the part without pad changes.
