K3A400001010G from KYX, 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 for the 40.000 MHz fundamental-mode resonator (10 pF load capacitance, 40 Ω max ESR), marked #1 on the top-view and land-pattern drawings. |
| 2 | NC | unconnected | Pad #2 appears in the package drawing, but the datasheet does not state its function; it is likely a no-connect or case pad. |
| 3 | XTAL2 | passive | Second crystal terminal for the 40.000 MHz resonator, marked #3 on the top-view drawing and diagonally opposite pad #1. |
| 4 | NC | unconnected | Pad #4 appears in the package drawing, but the datasheet does not state its function; it is likely a no-connect or case pad. |
