ECS-160-12-33Q-JES-TR

ECS · Crystals · SMD3225-4P

ECS-160-12-33Q-JES-TR 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 labeled In/Out; pads 1 and 3 are interchangeable because the crystal is symmetrical.
2 Gnd power_in Ground pad connected to Gnd; the datasheet states the chamfer on the bottom pad has no electrical significance.
3 Out/In passive Crystal terminal labeled Out/In; pads 1 and 3 are interchangeable because the crystal is symmetrical.
4 Gnd power_in Ground pad connected to Gnd; the datasheet states the chamfer on the bottom pad has no electrical significance.
