The TPSD157K016R0100: Rated 150 µF at 16 V, this TPS series molded tantalum provides the energy reservoir for a 3.3 V or 5 V rail where the downstream load draws bursts of current — the 16 V rating leaves headroom above a 12 V input bus. The 100 mOhm ESR keeps ripple voltage low in a switching regulator output or point-of-load filter; at 1 A ripple current the I²R loss is 0.1 W, manageable without forced airflow in the D case footprint.
The molded case and surface-mount 2917 (7343 Metric) package (7.30 mm x 4.30 mm, seated height 3.10 mm) suits automated pick-and-place assembly; the D case code is the standard 7343 footprint used across the TPS family.
