The TAJC226M006Y: 22 µF at 6.3 V rated — this is a bulk decoupling capacitor for a 3.3 V or 5 V rail, with enough margin to handle ripple without exceeding the voltage rating. The ±20% tolerance is typical for tantalum; for a filter or timing circuit where capacitance accuracy matters, you would need a tighter bin or a different dielectric.
This capacitor can sit in an avionics black box, a downhole sensor module, or an outdoor telecom enclosure without derating for cold start or hot soak. The molded case handles the thermal cycling without cracking the dielectric.
2312 (6032 Metric) case, size code C — 6.00 mm × 3.20 mm body, 2.80 mm seated height.
The TAJ series is a long-running KYOCERA AVX line, so reel availability should hold for the foreseeable future.
