The TAJB476K010RNJ: This is a 47 µF, 10 V rated molded tantalum capacitor from the TAJ series, with a ±10% tolerance and a 1 Ohm ESR. The 1 Ohm ESR is the spec that decides the application: it provides enough damping to prevent LC resonance on a switching-regulator output, but the ripple voltage at the cap terminals will be higher than with a low-ESR polymer cap — so keep it off a sensitive analog rail unless you budget the ripple.
Active production — no obsolescence clock ticking
No last-time-buy window, no EOL notice — you can design it in without worrying about a forced migration mid-production.
