1.5 µF at 35 V — the bulk decoupling fit for a 24 V rail
The TAJT155K035RNJ: This is a 1.5 µF, 35 V rated molded tantalum with ±10% tolerance from the TAJ series — the capacitance and voltage sit right for bulk decoupling on a 24 V DC rail, where the 35 V rating gives headroom against transients without oversizing the case. The 1411 (3528 Metric) footprint is common enough that the PCB land pattern is standard; no need to adjust pad geometry for this one.
The 5.2 Ohm ESR is the figure to watch for ripple current heating; at 125°C the derating curve governs the allowable AC ripple.
