Bulk decoupling for 25 V rails — 100 µF with 300 mΩ ESR
The TAJE107M025SNJV delivers 100 µF at 25 V rated voltage, with 300 mΩ ESR at 100 kHz. For a 3.3 V or 5 V rail derived from a 24 V bus, this capacitor provides the bulk charge reservoir needed to absorb load transients without the voltage droop exceeding the regulator's loop bandwidth.
The 2000-hour lifetime at 125°C is the endurance limit at the rated voltage and ripple current; running at 85°C ambient roughly doubles the expected life per the Arrhenius model for tantalum dielectrics. For a 10-year mission at 85°C with 50 % derated voltage, this part stays well within its wear-out budget.
