XC21M4-24.000-F12NNHQ

HCI · Crystals · SMD2016-4P

XC21M4-24.000-F12NNHQ from HCI, 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 CRYSTAL passive Crystal terminal; one of the two resonator connections (pads 1 and 3).
2 NC/GND passive N.C. or GND; connected to the metal lid, may be left open (floating) or connected to ground.
3 CRYSTAL passive Crystal terminal; the other resonator connection (pads 1 and 3).
4 NC/GND passive N.C. or GND; connected to the metal lid, may be left open (floating) or connected to ground.

CAD (KiCad official)

  • Symbol: XC21M4-24.000-F12NNHQ
  • Footprint: Crystal:Crystal_SMD_2016-4Pin_2.0x1.6mm
  • 3D model: SMD2016-4P (KiCad packages3D, STEP)
  • 3D model files: xc21m4-24-000-f12nnhq-etched.step / xc21m4-24-000-f12nnhq-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xc21m4-24-000-f12nnhq.step / xc21m4-24-000-f12nnhq.glb are the bare package body.
