10 µF, 16 V, 500 mOhm ESR — bulk decoupling for 12 V rails
The 500 mOhm ESR is the key thermal parameter: it determines the ripple current the part can handle before self-heating shifts the capacitance. For a 12 V rail with 100 mV ripple, the RMS ripple current stays under 200 mA, keeping the internal temperature rise below 10°C. The 2312 (6032 Metric) case is a standard footprint — the 0.236" x 0.126" (6.00 mm x 3.20 mm) body fits a 2.80 mm seated height, which is typical for a size C tantalum.
