10 µF, 10 V, 4 Ohm ESR — the TAJ S-case for decoupling and hold-up
The TAJS106K010RNJ: This is a Molded tantalum capacitor from the TAJ series, rated 10 µF at 10 V with a 4 Ohm ESR, in the compact 1206 (3216 Metric) S-case size.

S-case footprint and layout note
The 1206 case measures 3.20 mm x 1.60 mm with a seated height of 1.20 mm max — the low profile fits under a 1.6 mm PCB on the opposite side without interfering with the adjacent component keep-out. 4 Ohm ESR is the typical value at 100 kHz / 25 °C; the actual ripple-current capability depends on the board copper area under the terminations — a solid ground-plane pour reduces self-heating.
