ECS-384-10-37B2-CWN-TR from ECS, 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 | In/Out | passive | Crystal terminal; the crystal is symmetrical, so pad 1 and pad 3 are interchangeable. |
| 2 | Gnd | power_in | Ground pad as listed in the pad connections; the datasheet notes the chamfer on the bottom pad has no electrical significance. |
| 3 | Out/In | passive | Crystal terminal; the crystal is symmetrical, so pad 3 and pad 1 are interchangeable. |
| 4 | Gnd | power_in | Ground pad as listed in the pad connections. |
