220 µF automotive tantalum — the bulk decoupling cap for 12 V rails
It is the sort of bulk decoupling cap you reach for on a 12 V automotive power rail — the 16 V rating gives headroom above the nominal 12 V bus, and the 500 mOhm ESR at 100 kHz keeps ripple voltage in check for a switching regulator output.
AEC-Q200 — the automotive gate pass
This part carries AEC-Q200 qualification, the stress-test standard for passive components in automotive electronics. That means it has passed thermal shock, moisture resistance, vibration, and solder-heat reflow tests per the automotive industry's reliability baseline. For an engine control unit, transmission module, or body controller, this qualification is the entry ticket — no waiver needed.
The 125 °C rated life covers under-hood ambient where the cap sits near the engine block; the -55 °C low end handles cold-crank starts in arctic conditions. The 2000-hour figure at max temp is the accelerated-life baseline — actual field life at lower temperatures is significantly longer.
Active lifecycle — no last-time-buy clock
The part can be ordered against a BOM line without an urgent end-of-life deadline — normal replenishment cycles apply.
2917 case, size code E — the standard footprint
The footprint is 7.30 mm x 4.30 mm with a seated height of 4.30 mm. This matches the industry-standard EIA 2917 pad layout — a direct drop-in for any board already laid out for a size E tantalum cap.
