The TAJA224J035RNJ: This is a 0.22 µF molded tantalum capacitor rated at 35 V with an 18 Ohm equivalent series resistance. The 18 Ohm ESR is on the high side — it limits ripple current and increases self-heating, so this part is better suited for decoupling or timing roles than high-ripple bulk filtering. The ±5% tolerance gives tighter control than the standard ±10% or ±20% tantalum grades, useful for RC timing or filter poles where capacitance accuracy matters.
1206 footprint – rework and layout fit
Housed in a 1206 (3216 Metric) case, size code A, the part measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm max.
