What the 10 µF / 35 V / 1 Ohm ESR means for your BOM
The ±5% tolerance keeps the capacitance tight for timing or filtering circuits where a wide spread would shift the corner frequency or hold-up time.
Temperature range and lifetime — the reliability floor
For a power supply output that sees 85°C continuous, the derating curve from the datasheet gives the effective life; the 35 V rating provides headroom for 12 V or 24 V rails.
Package and footprint — 2917 D case
The 2917 (7343 Metric) D case is a standard tantalum capacitor footprint. The 7.30 mm x 4.30 mm body and 3.10 mm seated height fit the common D-case land pattern. Supplied on tape and reel, it is ready for pick-and-place assembly.
