10 µF, 10 V, 4 Ohm ESR — the decoupling and bulk-storage fit
In a decoupling role on a 3.3 V digital rail, the 10 V rating gives 3× derating against the rail voltage, which is standard practice for tantalum capacitors to avoid inrush failure. The S code size means the case height is 1.2 mm max, which fits under a 1.6 mm standoff on a mezzanine card or behind a low-profile BGA heatsink.
The full military temperature range qualifies this capacitor for avionics, satellite, downhole drilling, and missile-guidance systems where the ambient swings from cold-soak to engine-bay or re-entry heat.
