Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may contain updated mechanical or electrical tolerances. Confirm that the 4-SMD footprint matches the target PCB layout dimensions precisely. Ensure the 10 pF load capacitance aligns with the oscillator circuit requirements to maintain accurate frequency stability during integration.

Selection Notes

Select this component when a 44 MHz fundamental frequency is required in a low-profile surface-mount form factor. The 40 Ohm ESR value indicates suitability for standard oscillator circuits without excessive loading. Consider the 4-SMD package constraints regarding soldering thermal profiles and ensure the application environment remains within the specified operational limits for reliable performance.
