XXCBBCNAOF-12.000000MHZ from TAITIEN 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 at the top-left pad in the datasheet's solder pad layout; the datasheet gives no separate function, voltage or current limit for this pin. |
| 2 | GND | power_in | Connected to the crystal cover and to be connected to ground, as stated in the datasheet note '#2 and #4 are connected to the cover (please connect to ground)'. |
| 3 | 3 | passive | Crystal terminal at the bottom-right pad in the datasheet's solder pad layout; the datasheet gives no separate function, voltage or current limit for this pin. |
| 4 | GND | power_in | Connected to the crystal cover and to be connected to ground, as stated in the datasheet note '#2 and #4 are connected to the cover (please connect to ground)'. |
