15 µF, 16 V, 500 mOhm — the bulk decoupling fit
The 500 mOhm ESR sets the ripple current ceiling and the output voltage ripple on the rail it decouples — for a 3.3 V or 1.8 V supply, this part provides enough bulk capacitance to absorb load transients without excessive self-heating.
The molded construction with general-purpose features keeps the part usable across a wide range of environments without special screening.
For new designs or BOM fills, this part can be sourced per RFQ without lifecycle risk.
