The TAJC227M006SNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, offering 220 µF capacitance at 6.3 V rated voltage with ±20% tolerance. Its 1.2 Ohm ESR at 25 °C sets the ripple-current capability and self-heating — for a 100 kHz ripple with 1 A RMS, the internal temperature rise is roughly 1.2 W of dissipation, so the board layout should keep the capacitor away from hot components and allow airflow.
Size Code C — land pattern and clearance
The 6.00 mm x 3.20 mm body (Size Code C) fits the standard 2312 (6032 Metric) footprint, with a seated height of 2.80 mm max — verify clearance under adjacent tall components or enclosure lids. Surface-mount assembly on a 1.6 mm PCB is straightforward; the molded case provides good mechanical stability during reflow and under vibration.
