JYJE · Crystals · SMD3225-4P
3TJ437400ZYFBC 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 connected to one side of the resonator in the Top View Crystal Connection drawing (diagonal to pin 3). |
| 2 | GND | power_in | Marked GND in the Top View Crystal Connection drawing; ground/lid connection, not a crystal terminal. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the resonator in the Top View Crystal Connection drawing (diagonal to pin 1). |
| 4 | GND | power_in | Marked GND in the Top View Crystal Connection drawing; ground/lid connection, not a crystal terminal. |
