K3A400001810 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 | 1 | passive | Crystal terminal at pad #1 (marked with the chamfer/index corner in the 3.2x2.5 mm package drawing), the datasheet gives no electrical function text. |
| 2 | 2 | passive | Pad #2 of the 3.2x2.5 mm package; the datasheet drawing gives no stated function for it. |
| 3 | 3 | passive | Crystal terminal at pad #3, diagonally opposite pad #1 in the drawing; the datasheet gives no electrical function text. |
| 4 | 4 | passive | Pad #4 of the 3.2x2.5 mm package; the datasheet gives no stated function for it. |
