The TAJD226K035RNJ: At 22 µF and 35 V with a 900 mOhm ESR, this TAJ-series tantalum sits in the sweet spot for smoothing a 12 V or 24 V power rail where the ripple current stays moderate and the hold-up time is a few milliseconds. The 35 V rating gives 45 % derating on a 24 V bus — standard practice for tantalum to keep the applied voltage below 60 % of rated to avoid surge failures.
The D case (2917) body keeps the ESR and thermal impedance predictable across that span.
Active lifecycle — no last-time-buy clock
The product status is Active. No PCN, no EOL notice — this part can be designed in today without watching a last-time-buy window. KYOCERA AVX continues to produce the TAJ series in the D case, so the supply chain is stable for volume builds.
