This capacitance and voltage combination is a standard choice for bulk decoupling on supply rails where the 16 V rating provides ample headroom. The ±10% tolerance is the typical precision for tantalum capacitors used in power-supply filtering and hold-up circuits, where the exact value is less critical than the minimum capacitance at the operating voltage.
500 mOhm ESR and thermal budget
With an ESR of 500 mOhm, this capacitor is suitable for applications where ripple current is modest — think output filtering of a linear regulator or a low-power DC-DC converter.
The surface-mount 2312 (6032 Metric) case, size code C, is a widely used footprint — 6.00 mm x 3.20 mm with a seated height of 2.80 mm. The molded construction provides good mechanical stability during reflow soldering.
