HCI · Crystals · SMD2520-4P

0122M4-27.000F20DTJJL from HCI, in a SMD2520-4P. 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 1 of the AT-cut fundamental crystal (12.000 to 60.000MHz); connects to the oscillator circuit.
2 N.C. or GND passive Connected to the metal lid; may be left open (floating) or connected to ground.
3 CRYSTAL passive Crystal terminal 2 of the AT-cut fundamental crystal (12.000 to 60.000MHz); connects to the oscillator circuit.
4 N.C. or GND passive Connected to the metal lid; may be left open (floating) or connected to ground.
