The TAJA107M004SNJ packs 100 µF at 4 V into a molded 1206 case (3.20 mm × 1.60 mm) with a seated height of 1.80 mm — a dense bulk-decoupling option for 3.3 V or 1.8 V rails where board space is tight. ESR is specified at 1.4 Ohm — this sets the ripple-current rating and the high-frequency impedance floor. For a switching regulator output, the ripple voltage is the product of the inductor ripple current and this ESR; budget accordingly in the output filter design.
Derate the applied voltage at elevated temperatures per the manufacturer's guidelines; at 125°C the recommended working voltage is typically 50% of the rated 4 V to stay within the safe-operating area.
