CN4016M00009T8188009 from JWT, in a SMD2016-4P. 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 quartz blank in the 16.000MHz AT-cut resonator (CL 9pF, RR ≤150Ω). |
| 2 | GND | power_in | Ground pad, marked GND on the crystal connection drawing, connected to the lid and not to the crystal. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the quartz blank in the 16.000MHz AT-cut resonator (CL 9pF, RR ≤150Ω). |
| 4 | GND | power_in | Ground pad, marked GND on the crystal connection drawing, connected to the lid and not to the crystal. |
