3TJ430000XYFBC from JYJE, 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, connected to one side of the crystal element in the Top View Crystal Connection drawing. |
| 2 | GND | power_in | Pad 2 is labeled GND in the Top View Crystal Connection drawing; it is not a crystal terminal and is connected to the lid/case. |
| 3 | XTAL2 | passive | Crystal terminal 2, connected to the other side of the crystal element in the Top View Crystal Connection drawing. |
| 4 | GND | power_in | Pad 4 is labeled GND in the Top View Crystal Connection drawing; it is not a crystal terminal and is connected to the lid/case. |
