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

SX3B13.560F2010F30 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 13.560 MHz fundamental-mode resonator (CL 20pF, ESR 80Ω max); pin 1 is on the bottom-view top-left pad. |
| 2 | GND/NC | power_in | Connected to the metal cover; the datasheet says to connect it to GND or leave it floating. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 13.560 MHz fundamental-mode resonator (CL 20pF, ESR 80Ω max), diagonal to pin 1. |
| 4 | GND/NC | power_in | Connected to the metal cover; the datasheet says to connect it to GND or leave it floating (the 4th pad may be missing, and it is not used as a start position). |
