15 µF, 35 V, 100 mOhm ESR — what this capacitor delivers
The 100 mOhm ESR keeps ripple heating under control in power-supply output filters and decoupling stages — a lower ESR than the general-purpose baseline for this case size, which means less self-heating at a given ripple current. The 2917 (7343 Metric) footprint is a standard D-size case — the board layout matches any other D-case tantalum from the same series.
Where it fits — power filtering and bulk decoupling
A 15 µF, 35 V molded tantalum with 100 mOhm ESR is a natural fit for post-regulator output capacitance on a 12 V or 24 V rail, where the voltage derating (typically 50% for tantalum) leaves headroom. The molded case and surface-mount 2917 package suit automated assembly on a standard reflow profile.
