ECS-260-10-33B-CKM-TR
ECS · Crystals · SMD3225-4P
ECS-260-10-33B-CKM-TR from ECS, 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 | In/Out | passive | Crystal terminal (In/Out); pads 1 and 3 are electrically interchangeable, so either can serve as the input or output. |
| 2 | Gnd | power_in | Ground pad that must be connected to circuit ground. |
| 3 | Out/In | passive | Crystal terminal (Out/In); pads 1 and 3 are electrically interchangeable, so either can serve as the output or input. |
| 4 | Gnd | power_in | Ground pad that must be connected to circuit ground. |
