The TAJS225M006SNJ: This is a KYOCERA AVX TAJ-series molded tantalum capacitor, 2.2 µF at 6.3 V, in a 1206 (3216 Metric) surface-mount package. The 18 Ohm ESR is on the high side — expect more ripple heating than a low-ESR polymer part, so keep the AC ripple current under the thermal derating curve for the 1206 body.
This is a standard production part, not a discontinued line.
18 Ohm ESR at 25°C. For a 2.2 µF cap at 6.3 V, that ESR limits how much AC ripple current the part can handle before self-heating becomes a problem. In a low-impedance power rail, a low-ESR polymer cap would run cooler; this part is better suited for decoupling or timing circuits where ripple current is low.
