C3SB18.432F09M13 from CJKJ, 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 1, connected to one side of the quartz element (18.432000 MHz, CL 09 pF, Rr max 40 ohm). |
| 2 | GND | power_in | Pad labeled GND in the connection diagram, connected to the package lid/ground. |
| 3 | XTAL2 | passive | Crystal terminal 2, connected to the opposite side of the quartz element (18.432000 MHz, CL 09 pF, Rr max 40 ohm). |
| 4 | GND | power_in | Pad labeled GND in the connection diagram, connected to the package lid/ground. |
