Changjing · Crystals · SMD3225-4P

CJ13-160000910A20 from Changjing, 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 XTAL1 passive Crystal terminal connected to one side of the resonator in the pad-layout symbol; pad 1 is the chamfered pad, for a 16MHz 9pF load capacitance fundamental-mode crystal.
2 NC unconnected Pad not connected to the resonator in the pad-layout symbol; the datasheet gives no function for it.
3 XTAL2 passive Crystal terminal connected to the other side of the resonator in the pad-layout symbol, for a 16MHz 9pF load capacitance fundamental-mode crystal.
4 NC unconnected Pad not connected to the resonator in the pad-layout symbol; the datasheet gives no function for it.

CAD (KiCad official)

  • Symbol: CJ13-160000910A20
  • Footprint: Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm
  • 3D model: SMD3225-4P (KiCad packages3D, STEP)
  • 3D model files: cj13-160000910a20-etched.step / cj13-160000910a20-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj13-160000910a20.step / cj13-160000910a20.glb are the bare package body.
