1C237400AB0A from KDS Daishinku, 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 | Terminal connected to the quartz crystal element; the datasheet states no electrical limits for this terminal. |
| 2 | 2 | unconnected | Terminal is open (not connected to the quartz element) and should be left unconnected. |
| 3 | 3 | passive | Terminal connected to the quartz crystal element; the datasheet states no electrical limits for this terminal. |
| 4 | 4 | unconnected | Terminal is open (not connected to the quartz element) and should be left unconnected. |
