ECS-400-8-33Q-ADS-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 (pad 1 is electrically interchangeable with pad 3) on the 3.2 x 2.5 mm 4-pad package. |
| 2 | Gnd | power_in | Ground pad; the datasheet lists it as a Gnd connection, and the bottom-pad chamfer has no electrical significance. |
| 3 | Out/In | passive | Crystal terminal (pad 3 is electrically interchangeable with pad 1) on the 3.2 x 2.5 mm 4-pad package. |
| 4 | Gnd | power_in | Ground pad; the datasheet lists it as a Gnd connection, and the bottom-pad chamfer has no electrical significance. |
