68 µF, 16 V, 125 mOhm ESR — bulk decoupling on a 16 V rail
The 125 mOhm ESR is the key loss term: it sets the ripple current the cap can absorb before self-heating shifts the capacitance. For a 16 V rail carrying a 500 mA ripple, the I²R loss is about 31 mW — well within the package's dissipation limit, but worth checking if your load draws continuous high-frequency ripple above 1 A.
That is the full military band — the same cap that sits on a satellite power bus at -55°C also works in an engine-bay ECU that sees 125°C ambient. No voltage derating is required across this range for a 16 V part, but the ESR roughly doubles at -55°C, so the ripple current capability drops. If your board cold-soaks below -40°C, budget for higher ESR in the ripple budget.
