**Suzhou Liming Elec** · Crystals · SMD3225-4P

3225-25.00-20-10-10 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 | XTAL1 | passive | Crystal terminal connected to one side of the quartz element, used in the fundamental-mode oscillation circuit (CL series 6~32pF or as specified). |
| 2 | GND | power_in | Ground pad, connected internally to pad #4 through the metal cap on top. |
| 3 | XTAL2 | passive | Crystal terminal connected to the other side of the quartz element, used in the fundamental-mode oscillation circuit (drive level 10μW, 200μW max.). |
| 4 | GND | power_in | Ground pad, connected internally to pad #2 through the metal cap on top. |

## CAD (KiCad official)

- Symbol: `3225-25.00-20-10-10`
- Footprint: `Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm`
- 3D model: SMD3225-4P (KiCad packages3D, STEP)
- 3D model files: `3225-25-00-20-10-10-etched.step` / `3225-25-00-20-10-10-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `3225-25-00-20-10-10.step` / `3225-25-00-20-10-10.glb` are the bare package body.
