22 µF at 25 V — bulk decoupling fit
The TAJD226M025H: 22 µF capacitance at 25 V rated voltage covers the typical bulk decoupling requirement for 3.3 V and 5 V rails in mixed-signal circuits. The 900 mOhm ESR sets the ripple current ceiling — for a 100 kHz switching regulator, the self-heating from ripple current stays within the 125°C limit when the RMS current is kept under the datasheet derating curve.
