**NDK** · Crystals · SMD3225-4P

NX3225SA-12MHZ-EXS00A-CS13443 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 terminal #1 (land 1) of the 3.2 × 2.5 × 0.55 mm NX3225SA unit, with load capacitance per the ordered specification (e.g. 8 pF or 10 pF). |
| 2 | 2 | power_in | Terminal #2 is connected to the cover and the datasheet says to connect it to GND. |
| 3 | 3 | passive | Crystal terminal #3 (land 3) of the NX3225SA unit, the second crystal connection opposite terminal #1. |
| 4 | 4 | power_in | Terminal #4 is connected to the cover and the datasheet says to connect it to GND. |
