ECS-250-10-37BQ-CTN-TR

ECS · Crystals · SMD2016-4P

ECS-250-10-37BQ-CTN-TR from ECS, in a SMD2016-4P. 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 that may serve as input or output; the datasheet states pads 1 and 3 are interchangeable and the bottom-pad chamfer has no electrical significance.
2 Gnd power_in Ground pad connected to the crystal case; the datasheet gives no electrical limits for this pad.
3 Out/In passive Crystal terminal that may serve as output or input; the datasheet states pads 1 and 3 are interchangeable.
4 Gnd power_in Ground pad connected to the crystal case; the datasheet gives no electrical limits for this pad.

CAD (KiCad official)

  • Symbol: ECS-250-10-37BQ-CTN-TR
  • Footprint: Crystal:Crystal_SMD_2016-4Pin_2.0x1.6mm
  • 3D model: SMD2016-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-250-10-37bq-ctn-tr-etched.step / ecs-250-10-37bq-ctn-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-250-10-37bq-ctn-tr.step / ecs-250-10-37bq-ctn-tr.glb are the bare package body.
