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

3225-40-8-10-10 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 numbered in the top view of the outline drawing, but the datasheet does not state its function or any electrical limit for it. |
| 2 | 2 | passive | Pad 2 is connected internally to pad 4 through the metal cap, as shown in the internal connections diagram, and the datasheet gives no further electrical limit for it. |
| 3 | 3 | passive | Pad 3 is numbered in the top view of the outline drawing, but the datasheet does not state its function or any electrical limit for it. |
| 4 | 4 | passive | Pad 4 is connected internally to pad 2 through the metal cap, as shown in the internal connections diagram, and the datasheet gives no further electrical limit for it. |
