Procurement Notes

Verify the specific load capacitance and ESR requirements against the target circuit design before procurement. Confirm that the 2-SMD footprint dimensions align with the PCB silkscreen and copper pad layout. Ensure the manufacturing source is NDK to guarantee AEC-Q200 qualification status. Cross-reference the datasheet for reflow soldering profiles compatible with the NX5032GA series package.

Selection Notes

Select this component when a 13.56 MHz fundamental frequency is required with moderate frequency tolerance. The 8 pF load capacitance must match the oscillator circuit's external capacitors. Consider the 150 Ohm ESR value for drive level sensitivity. The NX5032GA series offers a balance of size and performance suitable for standard industrial and automotive environments.
