# NX3225SA-16.000M-STD-CRS-2

**NDK** · Crystals · SMD3225-4P

NX3225SA-16.000M-STD-CRS-2 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 | Terminal #1 is the top-left land in the top-view terminal drawing; the datasheet gives no separate function or electrical limit for this terminal. |
| 2 | #2 | power_in | Terminal #2 is internally connected to the lid (cover) and the datasheet says to connect it to GND. |
| 3 | #3 | passive | Terminal #3 is the bottom-right land in the top-view terminal drawing; the datasheet gives no separate function or electrical limit for this terminal. |
| 4 | #4 | power_in | Terminal #4 is internally connected to the lid (cover) with #2 and the datasheet says to connect it to GND. |
