This TAJV158M002RNJ is a molded tantalum capacitor from the TAJ series, delivering 1500 µF at 2.5 V in a 2924 (7361 Metric) surface-mount case. The 200 mOhm ESR is moderate for this capacitance value — expect ripple current capability in the 1.5 A range at 100 kHz, suitable for bulk decoupling on a 1.8 V or 2.5 V core supply rail where ceramic capacitance alone would need a large bank of 0805 or 1206 parts.
Full military-temperature qualification
The molded construction and ±20% tolerance are standard for this class — derate the applied voltage by 50% at 125°C per tantalum derating guidelines to stay within the safe operating area.
