Suzhou Liming Elec · Crystals · SMD3225-4P

3225-20-10-10-10 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 (load capacitance 6~32pF or series).
2 #2 passive Connected internally to pin #4 and to the metal cap on top; shown tied to GND in the fundamental-mode oscillation circuit.
3 #3 passive Crystal terminal 2 of the 3.2×2.5×0.7 mm fundamental-mode crystal unit, connected to the oscillation circuit (load capacitance 6~32pF or series).
4 #4 passive Connected internally to pin #2 and to the metal cap on top; shown tied to GND in the fundamental-mode oscillation circuit.
