Capacitance, voltage, and ESR at a glance
The TAJB226M010RNJ: 22 µF capacitance at 10 V rated voltage with ±20% tolerance — this is the primary BOM-fit parameter for power rail decoupling, DC blocking, or hold-up storage in a 10 V or lower rail. 2.4 Ohm ESR at 25°C sets the ripple current ceiling and self-heating under AC load — for a 100 kHz buck output, the ripple current should be derated against the temperature rise curve in the TAJ series datasheet.
Temperature grade and deployment range
Molded 1411 (3528 Metric) case, size code B, measuring 3.50 mm x 2.80 mm with a 2.10 mm seated height. Surface-mount reflow profile follows the standard tantalum ramp — peak temperature 260°C, with a 30-second max above 217°C per J-STD-020.
