7M12000009 from TXC Corp, 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 of the 12.000000 MHz fundamental-mode AT-cut crystal (CL 20 pF, drive level 100 uW max). |
| 2 | GND | power_in | Marked GND in the connection drawing; connects to the metal lid/ground. |
| 3 | 3 | passive | Second crystal terminal of the 12.000000 MHz fundamental-mode AT-cut crystal (ESR 100 ohm max, C0 5 pF max). |
| 4 | GND | power_in | Marked GND in the connection drawing; connects to the metal lid/ground. |
