SX3B16.000F0910F30 from Shenzhen SCTF 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 1 of the 16.000MHz fundamental-mode resonator (CL 09pF), connected to the other crystal terminal on pin 3 in the bottom-view drawing. |
| 2 | LID_GND | passive | Connected to the metal lid; the datasheet says to connect it to GND or leave it floating. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 16.000MHz fundamental-mode resonator (CL 09pF), connected to the other crystal terminal on pin 1 in the bottom-view drawing. |
| 4 | LID_GND | passive | Connected to the metal lid; the datasheet says to connect it to GND or leave it floating. |
