ECS-120-8-33-JGN-TR

ECS INC. · Global Sourcing Parts · SMD3225-4P

ECS-120-8-33-JGN-TR from ECS INC., 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 (In/Out); the crystal is symmetrical, so pads 1 and 3 are interchangeable and have no electrical significance.
2 Gnd power_in Ground connection pad (Gnd) as listed in the pad connections table.
3 Out/In passive Crystal terminal (Out/In); the crystal is symmetrical, so pads 1 and 3 are interchangeable and have no electrical significance.
4 Gnd power_in Ground connection pad (Gnd); the bottom chamfer may be on pad 4 or pad 1 and has no electrical significance.
