150 µF bulk tantalum for 20 V rails
The TAJV157K020RNJ is a molded tantalum capacitor from the TAJ series, delivering 150 µF at 20 V with ±10% tolerance — a common bulk decoupling value for 12 V or 5 V power buses that need headroom for ripple and transients. The 300 mOhm ESR is moderate for a 150 µF tantalum; it limits ripple current self-heating and keeps the capacitor within its thermal budget in a DC-DC output filter or a point-of-load bypass.
2924 footprint for layout
The 2924 (7361 Metric) case measures 7.30 mm x 6.10 mm with a seated height of 3.75 mm — a standard tantalum D-size footprint that fits most PCB layouts without special pad geometry.
