2.2 µF at 25 V — the BOM fit check
The TAJA225K025TNJ: This is a molded tantalum capacitor from the TAJ series, rated 2.2 µF at 25 V with ±10% tolerance. The 25 V rating gives 1.25× derating on a 20 V rail — standard practice for tantalum to avoid surge failures.
AEC-Q200 qualification — OEM-audit ready
Marked with AEC-Q200 ratings and the Automotive feature tag — this is the qualification the OEM auditor will ask for on the PPAP submission.
1206 footprint — board layout fit
Surface-mount 1206 case (3.20 mm x 1.60 mm), seated height 1.80 mm max. The manufacturer size code A matches the standard 1206 pad geometry — no layout respin needed if the BOM calls for this case.
