**Seiko Epson** · Crystals · SMD2016-4P

Q22FA12800369 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 | XTAL_1 | passive | Crystal unit terminal #1 on the recommended footprint (1.45 / 0.95 / 0.85 / 1.15 mm pad layout); the text gives no electrical limit for this pin. |
| 2 | COVER/GND | power_in | Connected to the crystal cover; the datasheet instructs the user to connect it to ground. |
| 3 | XTAL_2 | passive | Crystal unit terminal #3 on the recommended footprint; the text gives no electrical limit for this pin. |
| 4 | COVER/GND | power_in | Connected to the crystal cover; the datasheet instructs the user to connect it to ground. |
