6.8 µF, 10 V, 5.2 Ohm ESR — the decoupling slot it fills
The TAJR685M010RNJ: This is a molded tantalum capacitor from the TAJ series, rated 6.8 µF at 10 V with ±20% tolerance and a 5.2 Ohm ESR. The 0805 case (2.05 mm x 1.30 mm footprint, 1.20 mm seated height) fits standard reflow assembly.
The 125°C ceiling also covers engine-bay electronics if the ambient stays below the cap's derating curve.
