22 µF, 16 V molded tantalum — the BOM-fit check
Case code C — 6.00 mm × 3.20 mm footprint, 2.80 mm seated height — is the mid-range size in the TAJ family, common on mixed-signal and power-distribution boards where 22 µF decoupling is needed without a large land pattern.
The molded case construction gives mechanical rigidity and moisture resistance compared to conformal-coated chips, though the operating temperature range is the same as the solid tantalum chemistry allows.
The TAJ series is a broad, long-running line from KYOCERA AVX, so second-source availability is typically straightforward — confirm the case code and voltage rating when cross-referencing.
