# NX3225SA-25MHz-STD-CSR-6

**NDK** · Crystals · SMD3225-4P

NX3225SA-25MHz-STD-CSR-6 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 at the top-left position in the top-view terminal land layout; the datasheet gives no further electrical function, polarity or limit for this pin. |
| 2 | #2 | power_in | Terminal at the top-right position that is connected to the cover; the datasheet states that #2 and #4 are connected with a cover and asks that they be connected to GND. |
| 3 | #3 | passive | Crystal terminal at the bottom-right position in the top-view terminal land layout; the datasheet gives no further electrical function, polarity or limit for this pin. |
| 4 | #4 | power_in | Terminal at the bottom-left position that is connected to the cover; the datasheet states that #2 and #4 are connected with a cover and asks that they be connected to GND. |
