JWT · Crystals · SMD2520-4P

CM4040M00012T8188030 from JWT, 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 XTAL1 passive Crystal terminal 1 of the 2.5x2.0 mm package, shown connected to one side of the crystal element in the Top View Crystal Connection diagram.
2 GND power_in Pin 2 is labeled GND in the Top View Crystal Connection diagram, which is the case/ground connection.
3 XTAL2 passive Crystal terminal 3, shown connected to the opposite side of the crystal element from pin 1 in the crystal connection diagram.
4 GND power_in Pin 4 is labeled GND in the Top View Crystal Connection diagram, which is the case/ground connection.
