6.8 µF, 35 V, 1.8 Ohm ESR — bulk decoupling for a 35 V rail
The TAJC685K035RNJV: This is a molded tantalum capacitor from the TAJ series, rated 6.8 µF at 35 V with ±10% tolerance.
That 125°C lifetime figure is the accelerated test condition — in a cooler ambient the capacitor lasts longer. The full military temp range means it can sit in an outdoor telecom cabinet or an engine-bay ECU without derating the temperature spec.
