JWT · Crystals · SMD3225-4P

CF4008M00012T5074216 from JWT, 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 XTAL1 passive Crystal terminal connected to one electrode of the 8.000 MHz AT-cut resonator (CL 12 pF), marked by the chamfered pad on the bottom view.
2 GND power_in Marked GND in the crystal connection drawing; not connected to the crystal element.
3 XTAL2 passive Crystal terminal connected to the other electrode of the 8.000 MHz resonator, diagonal to pin 1.
4 GND power_in Marked GND in the crystal connection drawing; not connected to the crystal element.
