FL3840006

Diodes Incorporated · Crystals · SMD3225-4P

FL3840006 from Diodes Incorporated, 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 Xtal passive Crystal resonator terminal of the AT-cut quartz element; the datasheet gives no electrical limit for this pin beyond the crystal specifications (8 to 66 MHz fundamental, 5 pF max shunt capacitance, 10 µW typ / 100 µW max drive level).
2 Case passive Case pin of the seam-seal ceramic package; the datasheet lists it in the pin function table but does not state its electrical connection or function.
3 Xtal passive Second crystal resonator terminal of the AT-cut quartz element; the datasheet gives no electrical limit for this pin beyond the crystal specifications (8 to 66 MHz fundamental, 5 pF max shunt capacitance, 10 µW typ / 100 µW max drive level).
4 Case passive Case pin of the seam-seal ceramic package; the datasheet lists it in the pin function table but does not state its electrical connection or function.

CAD (KiCad official)

  • Symbol: FL3840006
  • Footprint: Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm
  • 3D model: SMD3225-4P (KiCad packages3D, STEP)
  • 3D model files: fl3840006-etched.step / fl3840006-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fl3840006.step / fl3840006.glb are the bare package body.
