47 µF bulk cap on a 20 V rail
The TAJD476K020RNJ is a 47 µF tantalum capacitor rated at 20 V with ±10% tolerance, from the TAJ series. The 900 mOhm ESR is typical for this case size and voltage; it is not a low-ESR polymer part, so ripple current capability is modest.
This capacitor can sit in an outdoor telecom enclosure, an engine-bay ECU, or a downhole instrument without exceeding the temperature rating.
