Procurement Notes

Verify the specific suffix requirements against your schematic before ordering. Confirm that the standard packaging quantity aligns with your production volume needs. Ensure the operating temperature range meets your environmental specifications. Check for any recent updates to the datasheet regarding mechanical tolerances or soldering profiles. Validate compatibility with your existing PCB footprint design.

Selection Notes

Choose this component when a 32 MHz timing source is required in a compact form factor. The NX2520SA series offers a balance between size and performance. Consider the ±10ppm stability for applications requiring moderate precision. Evaluate the 50 Ohm ESR against your oscillator circuit's drive level constraints. Compare against larger packages if higher thermal robustness is needed.
