**KEMET** · Aluminum Electrolytic Capacitors - Leaded · CP_Radial_D8.0mm_P3.50mm

ESH477M025AG4AA from KEMET, in a CP_Radial_D8.0mm_P3.50mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | + | passive | Positive lead (+) of the capacitor, with minimum lead length LL+ of 20 mm and lead spacing P of 3.5 ±0.5 mm for size G4. |
| 2 | - | passive | Negative lead (−), identified by the polarity stripe on the aluminum can, with minimum lead length LL− of 15 mm; the capacitor is rated 25 VDC for this part. |
