SX2B12.000F1010F30 from Shenzhen SCTF Elec, in a SMD2520-4P. 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 | Xtal | passive | Crystal terminal 1 (bottom-view pad 1, chamfered corner); connect to oscillator circuit, with load capacitance CL specified 6 to 20 pF (10 pF for this MPN). |
| 2 | GND | power_in | Ground pad, connected to the metal lid/ground per the pin function table. |
