3225-16-18-10-10 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 | Crystal terminal 1 of the 3.2×2.5×0.7 mm fundamental-mode crystal unit, connected to the oscillation circuit (C1/RF side). |
| 2 | #2 | passive | Connected internally to pad #4 and to the top metal cap (lid); shown connected to GND in the oscillation circuit. |
| 3 | #3 | passive | Crystal terminal 2 of the 3.2×2.5×0.7 mm fundamental-mode crystal unit, connected to the oscillation circuit (C2 side). |
| 4 | #4 | passive | Connected internally to pad #2 and to the top metal cap (lid); shown connected to GND in the oscillation circuit. |
