0.22 µF, 35 V, 1206 — TAJ series molded tantalum
The TAJA224M035YNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor rated at 0.22 µF with ±20% tolerance and 35 V DC working voltage. The 1206 (3216 Metric) footprint is a standard size that fits most general-purpose decoupling and filtering positions on a PCB. Equivalent series resistance is 18 ohms — this is the self-heating term under ripple current. For a 0.22 µF cap at 35 V, the ESR is less of a thermal concern than it would be for a higher-value bulk capacitor, but it still sets the impedance floor at high frequency.
1206 footprint and tape-and-reel packaging
The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm max. This is a standard two-terminal molded chip — no polarity marking confusion, but the anode band is present on the top face. Store the reels in a dry environment; tantalum caps are not moisture-sensitive like MLCCs, but long-term humidity exposure can affect the silver-palladium termination.
