100 µF at 25 V — bulk decoupling for 16 V rails
Tantalum electrolytics need a 50% voltage derating for reliable operation, so this part is a solid fit for 12 V or 16 V power rails — not a 24 V rail. The ±20% tolerance means the actual capacitance at the rail sits between 80 µF and 120 µF; budget that spread in your ripple calculations.
300 mOhm ESR — ripple current and self-heating
The molded case handles the thermal cycling better than a dipped tantalum — no epoxy cracking at the leads over repeated -55°C to 125°C swings.
