100 µF, 10 V, 700 mOhm ESR — bulk decoupling for a 10 V rail
The TAJD107M010HNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 100 µF and 10 V with a ±20% tolerance — a standard bulk decoupling value for 5 V and 3.3 V rails, or for filtering on a 10 V supply bus where the 700 mOhm ESR limits ripple current self-heating. The 2917 (7343 Metric) D-case footprint is common across the TAJ family, so a board already laid out for a D-case tantalum can accept this part without a PCB revision.
