7M37400001 from TXC Corp, 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 quartz resonator (internal view connection), with load capacitance CL of 6~20 pF. |
| 2 | GND | power_in | Ground pin marked GND in the internal view connection, typically connected to the lid/case. |
| 3 | XTAL2 | passive | Crystal terminal 3 connected to the other side of the quartz resonator (internal view connection), with load capacitance CL of 6~20 pF. |
| 4 | GND | power_in | Ground pin marked GND in the internal view connection, typically connected to the lid/case. |
