The TAJX476M016YNJ: Rated 47 µF at 16 VDC with a 900 mOhm ESR at 100 kHz, this TAJ-series molded tantalum sits on a 12 V power bus or a 5 V post-regulator rail where the voltage margin is 4 V above the rail — enough headroom for a 20 % transient without punching through the rated voltage.
At 125°C the leakage current rises and the capacitance drifts toward the low end of the ±20 % tolerance band — budget the derating in the hold-up time calculation for a power-fail circuit.
