ECS-240-8-36CKM-TR from ECS, in a SMD2520-4P. 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 (In/Out); symmetrical with pad 3 so pads 1 and 3 are interchangeable. |
| 2 | Gnd | power_in | Ground pad; connected to ground per the datasheet pad connections. |
| 3 | Out/In | passive | Crystal terminal (Out/In); symmetrical with pad 1 so pads 1 and 3 are interchangeable. |
| 4 | Gnd | power_in | Ground pad; connected to ground per the datasheet pad connections. |
