C2SB24.000F12E12A from Chuanjing Tech., 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 | X1 | passive | Crystal terminal 1 of the 24.000MHz fundamental resonator (CL 12pF), connected to one side of the crystal in the connection diagram; marked by the chamfered pad. |
| 2 | GND | power_in | Ground pin, labelled GND in the connection diagram, not connected to the crystal element (case ground). |
| 3 | X2 | passive | Crystal terminal 2 of the 24.000MHz fundamental resonator (CL 12pF), connected to the other side of the crystal in the connection diagram. |
| 4 | GND | power_in | Ground pin, labelled GND in the connection diagram, not connected to the crystal element (case ground). |
