**NDK** · Crystals · SMD3225-4P

NX3225SA 24M 15PPM 8PF -40+125 from NDK, 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 unit terminal shown as pin #1 in the terminal land connection diagram; the datasheet gives no separate function name for this pad. |
| 2 | 2 | power_in | Pin #2 is connected to the metal cover internally, and the datasheet says to connect it to GND. |
| 3 | 3 | passive | Crystal unit terminal shown as pin #3 in the terminal land connection diagram; the datasheet gives no separate function name for this pad. |
| 4 | 4 | power_in | Pin #4 is connected to the metal cover internally, and the datasheet says to connect it to GND. |
