AEC-Q200 qualified for engine-bay and chassis domains
The TAJA226K006TNJ: This part carries an AEC-Q200 qualification — the automotive passive-component stress test that maps to a specific temperature grade and reliability profile. For a 22 µF capacitor rated at 6.3 V in a 1206 case, the qualification means the part has passed temperature cycling, moisture resistance, and vibration tests per the AEC-Q200 document. An OEM auditor will expect PPAP documentation tied to this qualification level, not just a 'capable' marketing claim. That 125 °C ceiling matches under-hood ambient conditions — the capacitor sees the full engine-bay temperature swing without derating the voltage at the top end.
1206 footprint and 3 Ohm ESR — layout and ripple budget
The 3.20 mm x 1.60 mm 1206 case (manufacturer size code A) lands on a standard 3216 metric footprint. Seated height is 1.80 mm max — no clearance surprises under a low-profile PCB shield. ESR is 3 Ohm at 100 kHz — this is the dissipation floor for the ripple current the capacitor can filter.
