The TAJB157K004RNJ packs 150 µF into a molded 1411 (3528 Metric) case — that is a lot of capacitance for a 3.50 mm x 2.80 mm footprint. The 1.5 Ohm ESR is the trade-off: it limits ripple current to about 1.6 A at 100 kHz, so this cap is a solid fit for bulk decoupling on a 4 V rail where the load steps are moderate, not for a high-frequency switching regulator output where you need sub-100 mOhm ESR.

The molded package keeps the element dry; no conformal-coat worries on the capacitor body itself.
You can design this into a new BOM today and expect it to be available for the production run.
