ECS · Crystals · SMD3225-4P
ECS-480-7-33B2-CKM-TR3 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, interchangeable with pad 3 because the crystal is symmetrical; the datasheet states no voltage or current limit for this pad. |
| 2 | Gnd | power_in | Ground pad connected to Gnd; the datasheet gives no electrical limit for this pad. |
| 3 | Out/In | passive | Crystal terminal, interchangeable with pad 1 because the crystal is symmetrical; the datasheet states no voltage or current limit for this pad. |
| 4 | Gnd | power_in | Ground pad connected to Gnd; the datasheet gives no electrical limit for this pad. |
