CO21H4-32.000kHz-18JHPSTL

HCI · Crystal Oscillators · SMD2016-4P

CO21H4-32.000kHz-18JHPSTL 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 E/D or N.C. input Tri-state enable/disable control pad, or no connection depending on option.
2 GND power_in Ground; the metal lid is connected to GND at pin 2.
3 OUTPUT output LVCMOS RF output, specified with 15pF load (30pF optional).
4 VCC power_in Supply voltage pin, available for 1.8V, 2.5V or 3.3V supply options.

CAD (KiCad official)

  • Symbol: CO21H4-32.000kHz-18JHPSTL
  • Footprint: Crystal:Crystal_SMD_2016-4Pin_2.0x1.6mm
  • 3D model: SMD2016-4P (KiCad packages3D, STEP)
  • 3D model files: co21h4-32-000khz-18jhpstl-etched.step / co21h4-32-000khz-18jhpstl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); co21h4-32-000khz-18jhpstl.step / co21h4-32-000khz-18jhpstl.glb are the bare package body.
