The TAJE476M025RNJ: This is a 47 µF, 25 V molded tantalum capacitor from the TAJ series, in a 2917 (7343 Metric) case. The 900 mOhm ESR is typical for a 47 µF tantalum in this case size. In a DC-DC output filter, that ESR sets the ripple voltage.
The molded case and standard TAJ series construction mean it stores well on the reel — no special dry-pack requirements beyond the standard moisture barrier bag.
