7F37400E12UCG

SJK SHENZHEN CRYSTAL TECH · Crystals · SMD2016-4P

7F37400E12UCG from SJK SHENZHEN CRYSTAL TECH, 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 XTAL1 passive Crystal terminal connected to one side of the quartz blank (pin 1, bottom-left in top view); 37.400 MHz fundamental AT-cut, CL 12.0 pF.
2 GND power_in Marked GND in the top-view crystal connection drawing; connects to the lid/ground, diagonal to pin 4.
3 XTAL2 passive Crystal terminal connected to the other side of the quartz blank (pin 3, top-right in top view); 37.400 MHz fundamental AT-cut, CL 12.0 pF.
4 GND power_in Marked GND in the top-view crystal connection drawing; connects to the lid/ground, diagonal to pin 2.
