K2C400000910 from KYX, in a SMD2520-4P. 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 (9 pF load capacitance, 100 μW max drive level). |
| 2 | GND | power_in | Connected to the metal cover (lid); the datasheet says to connect it to GND. |
| 3 | XTAL2 | passive | Crystal terminal for the 40.000 MHz fundamental-mode resonator (9 pF load capacitance, 100 μW max drive level). |
| 4 | GND | power_in | Connected to the metal cover (lid); the datasheet says to connect it to GND. |
