The TAJR475K010SNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 4.7 µF at 10 V with ±10% tolerance.
The lifetime rating is 2000 hours at 125°C. In a hot environment — say a power supply or an engine-bay ECU — that is the baseline before the failure rate starts to shift. Below 85°C the life extends significantly, but the 2000-hour figure is the number to use for a worst-case reliability budget.
The evidence does not list a RoHS compliance status. Confirm with the manufacturer or your distributor at RFQ time.
The TAJ series includes many 0805-case tantalums at 4.7 µF and 10 V. The key differentiator is the ESR — 9 Ohm at 100 kHz for this part. A lower-ESR variant (e.g., the TAJR475K010SNJ's own siblings with different suffix codes) would handle more ripple current but may cost more. Check the ESR column in the TAJ series datasheet for a direct parametric match.
