**JYJE** · Crystals · SMD3225-4P

3TJ498437NYLBC 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 (pin-1 pad has the chamfered corner), connected to one side of the resonator; the drawing does not label it GND. |
| 2 | GND | power_in | Marked GND in the connection diagram; typically tied to the lid/ground. |
| 3 | XTAL2 | passive | Crystal terminal 2, connected to the other side of the resonator; the drawing does not label it GND. |
| 4 | GND | power_in | Marked GND in the connection diagram; typically tied to the lid/ground. |
