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

3225-26-7.3-10-10 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 of the 4-pad 3.2×2.5×0.7 mm crystal unit; the datasheet does not state its function in the extracted text, so it is treated as a crystal terminal pending confirmation. |
| 2 | #2 | passive | Pad #2 is internally connected to pad #4 through the metal cap, as stated in the datasheet note '#2 and #4 are connected with metal cap.' |
| 3 | #3 | passive | Pad #3 of the 4-pad crystal unit; the datasheet does not state its function in the extracted text, so it is treated as a crystal terminal pending confirmation. |
| 4 | #4 | passive | Pad #4 is internally connected to pad #2 through the metal cap, as stated in the datasheet note '#2 and #4 are connected with metal cap.' |
