The TAJC106K020H: 10 µF at 20 V with ±10% tolerance — this is a common bulk decoupling value for 12 V and 5 V rails, leaving enough voltage derating margin (typically 50% of rated voltage) to keep the tantalum anode from failing under surge. 1.2 Ohm ESR sets the ripple current ceiling — at 100 kHz the capacitor can handle roughly 0.5 A ripple before self-heating becomes a concern; for a switching regulator output, check the ripple current against this limit to avoid exceeding the 125°C max operating temperature.
Size code C (2312 / 6032 metric) — the molded body is 6.00 mm x 3.20 mm with a seated height of 2.80 mm. The case is non-polarized but the anode band marks the positive terminal; rework with a hot-air station at 260°C peak for ten seconds, same as an MLCC of similar footprint.
