ECS-160-18-33Q-DS

ECS · Pre-ordered Products · SMD3225-4P

ECS-160-18-33Q-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 labelled In/Out; pads 1 and 3 are interchangeable because the crystal is symmetrical.
2 Gnd power_in Ground pad connected to circuit ground.
3 Out/In passive Crystal terminal labelled Out/In; pads 1 and 3 are interchangeable because the crystal is symmetrical.
4 Gnd power_in Ground pad connected to circuit ground.

CAD (KiCad official)

  • Symbol: ECS-160-18-33Q-DS
  • Footprint: Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm
  • 3D model: SMD3225-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-160-18-33q-ds-etched.step / ecs-160-18-33q-ds-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-160-18-33q-ds.step / ecs-160-18-33q-ds.glb are the bare package body.

Provenance

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

  • Datasheet: ECS datasheet (2 pp, sha256 a6b1a2f2b9a74cec, retrieved 2026-10-30, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
