Resonators Procurement Notes

Verify the specific frequency code within the part number to ensure it matches the required 6.875 MHz specification. Confirm that the load capacitance requirement aligns with the integrated 15 pF value to avoid frequency drift. Check the operating temperature range against environmental conditions. Ensure the surface-mount footprint dimensions are compatible with the target PCB design. Validate compliance with relevant regional regulatory standards such as RoHS before finalizing procurement.

Resonators Selection Notes

Select this component when a stable, low-cost clock source is needed without external capacitors. Compare the 50 Ohm impedance against other resonators if drive level sensitivity is a concern. Consider the ±0.5% tolerance for applications requiring precise synchronization. Evaluate the physical size constraints against alternative packages in the same series. Assess thermal performance within the specified -20°C to +80°C range for the intended environment.
