ECS-250-18-33Q-DS

ECS · Crystals · SMD3225-4P

ECS-250-18-33Q-DS 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; pads 1 and 3 are interchangeable because the crystal is symmetrical, so either can be the input or output.
2 Gnd power_in Ground pad connected to the crystal case/ground, which the datasheet lists as Gnd.
3 Out/In passive Crystal terminal; pads 3 and 1 are interchangeable because the crystal is symmetrical, so either can be the output or input.
4 Gnd power_in Ground pad connected to the crystal case/ground, which the datasheet lists as Gnd.

CAD (KiCad official)

  • Symbol: ECS-250-18-33Q-DS
  • Footprint: Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm
  • 3D model: SMD3225-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-250-18-33q-ds-etched.step / ecs-250-18-33q-ds-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-250-18-33q-ds.step / ecs-250-18-33q-ds.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
