**KDS Daishinku** · Crystals · SMD3225-4P

1C319200AA0A 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 | Pin #1 is numbered on the Fig.-1 top and bottom views, but the datasheet does not state its function or electrical limits. |
| 2 | #2 | unconnected | The Fig.-1 note says Marking #2 and #4 are not connected to anything, while a second note recommends connecting #2 and #4 to GND. |
| 3 | #3 | passive | Pin #3 is numbered on the Fig.-1 top and bottom views, but the datasheet does not state its function or electrical limits. |
| 4 | #4 | unconnected | The Fig.-1 note says Marking #2 and #4 are not connected to anything, while a second note recommends connecting #2 and #4 to GND. |
