The TPSE227K016T0100V: The 100 mOhm ESR at 100 kHz sets the self-heating limit under ripple current. For a 220 µF part, this ESR is mid-range — low enough to handle a few hundred mA of ripple without excessive temperature rise, but not so low that it invites inrush issues. The 2000-hour lifetime at 125°C means the capacitor's electrolyte dry-out rate is calibrated for high-temp operation; at 85°C the expected life extends well beyond that figure.
AEC-Q200 — the automotive gate
AEC-Q200 qualification means this part passed the stress tests required for automotive-grade passive components: temperature cycling, moisture resistance, mechanical shock, and vibration. This is the authority signal for any BOM targeting under-hood, body-control, or infotainment modules where the supply chain demands PPAP-capable parts.
2917 case — the board-fit constraint
The E case code matches the standard 2917 land pattern. This is a molded case — the epoxy encapsulation gives consistent dimensional control for pick-and-place, and the flat top aids vacuum pickup. The part ships on tape and reel, compatible with standard 12 mm or 16 mm carrier tape for automated assembly.
