Molded tantalum, 15 µF at 35 V, 100 mOhm ESR
The 100 mOhm ESR keeps ripple heating manageable in bulk decoupling or output filtering roles — for a 1 A ripple current, dissipation stays under 100 mW, which the 2917 package can sink to the board without derating at 85°C ambient.
The molded case and surface-mount 2917 footprint (7.30 mm x 4.30 mm, 3.10 mm seated height) suit reflow assembly; the wide temp range means capacitance drift and ESR shift stay within datasheet limits across the mission profile.
