150 µF, 16 V, 75 mOhm ESR — TPS series tantalum
The TPSV157K016R0075: The 75 mOhm ESR (equivalent series resistance) governs the ripple current handling and self-heating — lower ESR means less power dissipated as heat for a given AC ripple, so this part suits output filtering in DC-DC converters where the ripple current is a design constraint.
