47 µF at 16 V — the bulk decoupling anchor
The 900 mOhm ESR sets the ripple current handling and self-heating ceiling — for a 100 kHz buck output, that ESR adds about 1.3°C self-heat at the rated ripple, which is well inside the 125°C limit. The D case (2917 / 7343 metric) footprint is a common bulk-capacitor land pattern; the 0.122" seated height clears most low-profile board stacks without issue.
Active — no end-of-life pressure
For avionics power supplies or downhole instrumentation that sees 105°C ambient, the 125°C ceiling provides derating headroom. The molded case construction and ±20% tolerance are standard for general-purpose tantalum applications.
