What this tantalum cap brings to an automotive BOM
2000-hour endurance at 125°C — what it buys you
In practice, a 16 V cap on a 12 V rail runs derated, which extends life beyond the test condition. For a transmission controller expected to see 10 years of intermittent 105°C peaks, this cap has margin.
1206 case — rework-friendly footprint
The 1206 (3216 metric) case is a standard size with visible end terminations — easy to hand-solder or rework under a hot-air station without lifting pads. The 0.071-inch seated height keeps it below low-profile enclosures. ESR is 11 ohms at 100 kHz, typical for a small-case tantalum; that matters for ripple filtering on a 16 V rail where the ripple current is modest.
