**Suzhou Liming Elec** · Crystals · SMD3225-4P

3225-30-20-10-10 from Suzhou Liming Elec, in a SMD3225-4P. 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 | 1 | passive | Pad #1 is one of the four numbered pads of the 3.2×2.5×0.7 mm crystal unit, but the extracted text does not state its electrical function, so it must be confirmed against the internal-connections drawing and the solder pad layout. |
| 2 | 2 | passive | Pad #2 is internally connected to pad #4 through the metal cap (per the datasheet note '*#2 and #4 are connected with metal cap'), and no voltage or current limit is stated for it. |
| 3 | 3 | passive | Pad #3 is one of the four numbered pads of the crystal unit, but the extracted text does not state its electrical function, so it must be confirmed against the internal-connections drawing and the solder pad layout. |
| 4 | 4 | passive | Pad #4 is internally connected to pad #2 through the metal cap (per the datasheet note '*#2 and #4 are connected with metal cap'), and no voltage or current limit is stated for it. |
