**Hosonic Elec** · Crystals · SMD3225-4P

E3SB25E00000VE from Hosonic Elec, 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 the quartz blank (pin 1 is marked by the logo location); the datasheet lists #1 and #3 as the X'tal connections. |
| 2 | GND | power_in | Ground connection (the datasheet lists #2 and #4 as GND), typically tied to the lid/case. |
| 3 | XTAL2 | passive | Crystal terminal connected to the quartz blank; the datasheet lists #1 and #3 as the X'tal connections. |
| 4 | GND | power_in | Ground connection (the datasheet lists #2 and #4 as GND), typically tied to the lid/case. |
