ECS-120-18-5PX-TR
ECS INTERNATIONAL INC · Global Sourcing Parts · HC-49S-SMD
ECS-120-18-5PX-TR from ECS INTERNATIONAL INC, 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 | XTAL1 | passive | Crystal terminal 1 (connecting pin); the crystal is symmetrical so pins 1 and 2 are interchangeable. |
| 2 | XTAL2 | passive | Crystal terminal 2 (connecting pin); the crystal is symmetrical so pins 1 and 2 are interchangeable. |
