The TAJE227K006RNJ: Rated 220 µF at 6.3 V with a 900 mOhm ESR, this TAJ-series molded tantalum is sized for bulk decoupling on a 3.3 V or 1.8 V rail — the 6.3 V rating provides derating margin for a 3.3 V supply, and the ESR sets the ripple current ceiling. The 2917 (7343 Metric) case with an E-size code means the footprint matches the standard 7.3 mm x 4.3 mm land pattern — no layout surprise if you are replacing a similar-case tantalum.
Military temperature range — avionics and downhole fit
The molded case and surface-mount construction suit automated assembly in high-reliability builds; the ±10% tolerance keeps the capacitance window tight enough for most filter and hold-up circuits.
