**TKD** · Crystals · SMD3225-4P

SX32Y040000BF1T001 from TKD, 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 | Crystal | passive | Crystal terminal connected to one side of the resonator (pins #1 and #3 are the crystal connections). |
| 2 | GND | power_in | Ground connection, tied to the lid/case (pins #2 and #4 are GND). |
| 3 | Crystal | passive | Crystal terminal connected to the other side of the resonator (pins #1 and #3 are the crystal connections). |
| 4 | GND | power_in | Ground connection, tied to the lid/case (pins #2 and #4 are GND). |

## CAD (KiCad official)

- Symbol: `SX32Y040000BF1T001`
- Footprint: `Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm`
- 3D model: SMD3225-4P (KiCad packages3D, STEP)
- 3D model files: `sx32y040000bf1t001-etched.step` / `sx32y040000bf1t001-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sx32y040000bf1t001.step` / `sx32y040000bf1t001.glb` are the bare package body.
