ECS-080-18-5PX-JES-TR from ECS, in a HC-49S-SMD. 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 | 1 | passive | Crystal terminal; the crystal is symmetrical, so pins 1 and 2 are interchangeable. |
| 2 | 2 | passive | Crystal terminal; the crystal is symmetrical, so pins 1 and 2 are interchangeable. |
