Suzhou Liming Elec · Crystals · SMD3225-4P

3225-13.56-20-10-10 from Suzhou Liming Elec, 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 1 passive Crystal terminal #1 of the 3.2×2.5×0.7 mm fundamental-mode crystal unit, connected to the oscillation circuit (C1/inverter side).
2 2 passive Connected internally to pin 4 and to the metal cap (lid) on top; the oscillation-circuit drawing shows #2 and #4 on GND.
3 3 passive Crystal terminal #3 of the crystal unit, connected to the oscillation circuit (C2/inverter side).
4 4 passive Connected internally to pin 2 and to the metal cap (lid) on top; the oscillation-circuit drawing shows #2 and #4 on GND.
