ECS-120-8-33Q-RES-TR

ECS · Crystals · SMD3225-4P

ECS-120-8-33Q-RES-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 in the pad-connection table; pads 1 and 3 are interchangeable and the crystal is symmetrical.
2 Gnd power_in Ground pad connected to the crystal case/ground per the pad-connection table, with no further electrical limits stated.
3 Out/In passive Crystal terminal labeled Out/In in the pad-connection table; interchangeable with pad 1 because the crystal is symmetrical.
4 Gnd power_in Ground pad per the pad-connection table, with no further electrical limits stated.

CAD (KiCad official)

  • Symbol: ECS-120-8-33Q-RES-TR
  • Footprint: Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm
  • 3D model: SMD3225-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-120-8-33q-res-tr-etched.step / ecs-120-8-33q-res-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-120-8-33q-res-tr.step / ecs-120-8-33q-res-tr.glb are the bare package body.
