Suzhou Liming Elec · Crystals · SMD3225-4P
3225-27-12-10-10 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 | XTAL1 | passive | Crystal terminal 1 for the 27.000MHz resonator, with a nominal load capacitance of 12 pF. |
| 2 | GND | power_in | Pad #2 is connected to the metal cap on top and so to pad #4 (GND), and should be tied to ground. |
| 3 | XTAL2 | passive | Crystal terminal 2 for the 27.000MHz resonator, with a nominal load capacitance of 12 pF. |
| 4 | GND | power_in | Pad #4 is labeled GND and is connected to the metal cap on top, together with pad #2. |
