The TAJR474M025RNJ: 0.47 µF at 25 V in an 0805 molded case — this is a general-purpose tantalum for local decoupling on a 12 V or 24 V rail where the ripple voltage stays below the 25 V rating. The ±20% tolerance means the actual capacitance can range from 0.376 µF to 0.564 µF; a timing circuit that depends on a tight C value needs a different tolerance grade.
At 125°C, the voltage derating curve applies; running at the full 25 V at the upper temperature limit shortens life.
