JWT · Crystals · SMD2016-4P

CN4025M00020T8188110 from JWT, 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 electrode of the 25.000MHz AT-cut resonator (CL 20pF, drive level 1-100uW, RR ≤40Ω).
2 GND power_in Ground pad, marked GND on the crystal-connection drawing, not connected to the crystal electrodes (lid/ground).
3 XTAL2 passive Crystal terminal connected to the other electrode of the 25.000MHz AT-cut resonator (CL 20pF, drive level 1-100uW, RR ≤40Ω).
4 GND power_in Ground pad, marked GND on the crystal-connection drawing, not connected to the crystal electrodes (lid/ground).
