ECS-240-8-37-CKM-TR3
ECS · Crystals · SMD2016-4P
ECS-240-8-37-CKM-TR3 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 (In/Out) that is electrically interchangeable with pad 3; the datasheet states the crystal is symmetrical and pads 1 and 3 can be swapped. |
| 2 | Gnd | power_in | Ground pad connection as listed in the datasheet pad connections table; the datasheet gives no further electrical limits for this pad. |
| 3 | Out/In | passive | Crystal terminal (Out/In) that is electrically interchangeable with pad 1; the chamfer on the bottom pad has no electrical significance. |
| 4 | Gnd | power_in | Ground pad connection as listed in the datasheet pad connections table; the datasheet gives no further electrical limits for this pad. |
