**Shenzhen SCTF Elec** · Crystals · SMD3225-4P

SX3B16.000F1510F30 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 (16.000MHz fundamental AT-cut, CL 15pF, drive level 100μW max); the two crystal terminals are interchangeable. |
| 2 | CASE_GND_2 | passive | Connected to the metal cover (lid); datasheet says to connect it to GND or leave it floating. |
| 3 | XTAL2 | passive | Crystal terminal (16.000MHz fundamental AT-cut, CL 15pF, drive level 100μW max); the two crystal terminals are interchangeable. |
| 4 | CASE_GND_4 | passive | Connected to the metal cover (lid); datasheet says to connect it to GND or leave it floating. |
