X3S038400B91H-HU from HELE(Harmony 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 (chamfered index pad) connected to one electrode of the 38.400 MHz blank, 9.0 pF load capacitance, 40 ohm max ESR. |
| 2 | NC | unconnected | Pad is not shown connected to the crystal blank in the top-view drawing; no function is stated. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other electrode of the 38.400 MHz blank, diagonal to pad 1, 9.0 pF load capacitance, 40 ohm max ESR. |
| 4 | NC | unconnected | Pad is not shown connected to the crystal blank in the top-view drawing; no function is stated. |
