22 µF, 20 V — bulk decoupling for 12 V rails
On a 12 V supply rail, the 67% derating margin aligns with typical tantalum reliability guidelines; on a 15 V rail the margin narrows to 33%, which may require additional ripple-current derating in high-temperature environments.
C case, 2312 footprint — board layout fit
Packaged in the industry-standard C case (2312 / 6032 Metric), the capacitor measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm. The surface-mount footprint matches standard tantalum land patterns; the molded body provides mechanical stability during reflow and subsequent vibration.
At the upper end, the capacitor's ESR and leakage current increase; the 20 V rating should be derated further per the manufacturer's application notes when operating above 85°C.
