Q22FA12800078 from Seiko Epson, in a SMD2016-4P. 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 #1 of the 4-terminal crystal unit; the datasheet's internal connection diagram shows it but does not state its electrical function. |
| 2 | #2 | power_in | Connected to the metal cover; the datasheet says to connect this pin to ground. |
| 3 | #3 | passive | Terminal #3 of the 4-terminal crystal unit; the datasheet's internal connection diagram shows it but does not state its electrical function. |
| 4 | #4 | power_in | Connected to the metal cover; the datasheet says to connect this pin to ground. |
