47 µF, 10 V — bulk decoupling slot for the 2917 footprint
The TAJD476M010RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, delivering 47 µF at 10 V in the D case size (2917 / 7343 metric). With 400 mOhm ESR, this part handles typical power-supply output ripple without excessive self-heating — the ESR figure is the main derating input for ripple current in the application.
At the 125°C end, the voltage derating guideline for tantalum capacitors recommends operating at 50% of rated voltage — for a 10 V part, that means a 5 V rail is the safe continuous limit.
Active production — orderable for new designs
The D case (2917) is a common footprint shared across multiple TAJ series capacitance/voltage combinations — the BOM position can be re-sourced without a board spin if the value changes.
