Polymer construction for low-ESR bulk decoupling
The Panasonic EEF-GX0E471L is a surface-mount polymer (conductive polymer) capacitor in the SP-Cap GX series, rated 470 µF at 2.5 V with a stated ESR of 3 mΩ. The 3 mΩ figure is the selection anchor — it defines how much impedance the cap presents at the switching frequency of the rail it decouples, and directly sets the allowable ripple current once the bus impedance is known. The 10.2 A ripple current rating at 100 kHz reflects the capacitor's ability to absorb charge-cycle demand from the switching converter without exceeding its thermal ceiling; the ESR figure is what converts that ripple into dissipative loss (I² × R) at the operating frequency. At 2000 hours @ 105 °C, the lifetime rating is adequate for consumer-electronics thermal profiles — it is a consumer-grade part with no AEC-Q qualification in the listed evidence.
2.00 mm seated height and board footprint
That 2.00 mm seated height is the physical constraint — it clears the board-plane budget on ultra-slim portable designs where every tenth of a millimetre constrains the enclosure. The ±20% tolerance on 470 µF is standard for conductive-polymer dielectrics; the applied voltage should stay well below the 2.5 V rated ceiling to avoid wear acceleration on the polymer dielectric.
