Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as bulk quantities may differ from reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to final procurement. Ensure that the selected variant matches the required operating temperature range and mechanical dimensions for your specific application board design.

Selection Notes

Select this component when a 40 MHz reference is required for surface-mount assembly. Consider the 18 pF load capacitance requirement to ensure oscillator circuit compatibility. Evaluate the 70 Ohm ESR against your oscillator driver strength to prevent overdriving. Compare physical dimensions against available PCB footprint constraints before integration.
