JWT · Crystals · SMD2016-4P

CN4038M40010T8188119 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 38.400 MHz AT-cut resonator (CL 10 pF, RR ≤40 Ω, drive level 1-100 µW).
2 GND power_in Ground pin connected to the lid/case, marked GND in the crystal connection drawing.
3 XTAL2 passive Crystal terminal connected to the other electrode of the 38.400 MHz AT-cut resonator (CL 10 pF, RR ≤40 Ω, drive level 1-100 µW).
4 GND power_in Ground pin connected to the lid/case, marked GND in the crystal connection drawing.
