Capacitance, voltage, and ESR for rail decoupling
The TAJC226K010H: 22 µF capacitance at 10 V rated voltage with ±10% tolerance — this is a standard bulk-decoupling value for 3.3 V or 5 V rails, where the 10 V rating provides a 2× derating margin against applied DC bias and ripple. 1.8 Ohm ESR at 100 kHz sets the ripple current capability and self-heating limit; for a 100 kHz switching regulator output, the ESR dominates the output ripple voltage and the capacitor's internal temperature rise.
The tantalum dielectric maintains capacitance stability across the range, though ESR increases at low temperature.
2312 (6032 Metric) case, size code C, 6.00 mm x 3.20 mm x 2.80 mm seated height. The molded rectangular body suits standard reflow soldering; the pad layout follows the JEITA/EIA footprint for this case size.
