Bulk capacitance for low-voltage rails
The TAJD477M006RNJV: 470 µF at 6.3 V with 400 mΩ ESR at 100 kHz — this TAJ-series tantalum is sized for output filtering on 3.3 V or 5 V DC-DC converters where ripple current and transient response drive the capacitor selection. The 2917 case (7.30 mm x 4.30 mm) fits a standard footprint; the 3.10 mm seated height keeps it under low-profile heatsinks or shrouds.
That 125°C ceiling matches under-hood automotive ambient or industrial enclosures near a motor drive. In a 85°C environment the life expectancy extends well beyond the datasheet rating — the 2000-hour figure is the guaranteed minimum at the upper temperature limit.
This is a standard catalog item in the TAJ series, not a phased-out or NRND part. No last-time-buy window to track; it can be designed in for new builds with confidence.
