**Shenzhen SCTF Elec** · Crystals · SMD2520-4P

SX2B16.000F0910F30 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 | XTAL1 | passive | Crystal terminal 1 (marked pad with chamfered corner), connected to one side of the 16.000MHz crystal element with 9pF load capacitance. |
| 2 | NC/GND | passive | Connected to the metal cover, not to the crystal element; connect to GND or leave floating. |
| 3 | XTAL2 | passive | Crystal terminal 2, connected to the other side of the 16.000MHz crystal element. |
| 4 | NC/GND | passive | Connected to the metal cover, not to the crystal element; connect to GND or leave floating. |
