ECS INC. · Global Sourcing Parts · SMD3215-2P
ECS-.327-9-34QCS-TR9 from ECS INC., in a SMD3215-2P. 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 | Pad 1 is one crystal terminal labelled In/Out in the pad connections, and the datasheet states no voltage or current limits for it. |
| 2 | Out/In | passive | Pad 2 is the other crystal terminal labelled Out/In in the pad connections, and the datasheet states no voltage or current limits for it. |
