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

3225-27.1412-20-10-10 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 | XTAL1 | passive | Crystal terminal connected to one side of the internal quartz element (the datasheet gives no signal name; pad 1 has the chamfered marker). |
| 2 | GND | power_in | Ground pad, connected internally to pad 4 through the metal lid (cap) on top. |
| 3 | XTAL2 | passive | Crystal terminal connected to the opposite side of the internal quartz element from pad 1 (the datasheet gives no signal name). |
| 4 | GND | power_in | Ground pad, connected internally to pad 2 through the metal lid (cap) on top. |
