NX3225SA-16MHz-STD-CSR-6

NDK · Crystals · SMD3225-4P

NX3225SA-16MHz-STD-CSR-6 from NDK, 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 X'tal passive Crystal resonator terminal (marked *#1, #3 : X'tal) for the NX3225SA crystal unit, with the crystal connected between pins 1 and 3.
2 Cover (GND) passive Connected to pin 4 through the metal cover; the datasheet states it should be connected to GND, and it is not a crystal terminal.
3 X'tal passive Crystal resonator terminal (marked *#1, #3 : X'tal) for the NX3225SA crystal unit, with the crystal connected between pins 1 and 3.
4 Cover (GND) passive Connected to pin 2 through the metal cover; the datasheet states it should be connected to GND, and it is not a crystal terminal.

CAD (KiCad official)

  • Symbol: NX3225SA-16MHz-STD-CSR-6
  • Footprint: Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm
  • 3D model: SMD3225-4P (KiCad packages3D, STEP)
  • 3D model files: nx3225sa-16mhz-std-csr-6-etched.step / nx3225sa-16mhz-std-csr-6-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nx3225sa-16mhz-std-csr-6.step / nx3225sa-16mhz-std-csr-6.glb are the bare package body.
