**TAITIEN Elec** · Crystals · SMD2520-4P

XYCEELNANF-12.000000MHZ from TAITIEN 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 | #1 | passive | Solder pad #1 is shown in the solder pad layout, but the datasheet does not state its electrical function or limits. |
| 2 | GND | power_in | Pad #2 is connected to the cover and the datasheet says to connect it to ground. |
| 3 | #3 | passive | Solder pad #3 is shown in the solder pad layout, but the datasheet does not state its electrical function or limits. |
| 4 | GND | power_in | Pad #4 is connected to the cover and the datasheet says to connect it to ground. |
