Resonators Procurement Notes

Verify the exact suffix designation when ordering, as it determines the specific center frequency (e.g., -14 for 433.92 MHz). Confirm RoHS compliance status through official datasheets prior to integration. Ensure the selected variant matches the required load capacitance and frequency tolerance for the target circuit design. Cross-reference part numbers with manufacturer documentation to avoid confusion between similar series components.

Resonators Selection Notes

Select the appropriate model based on the required operating frequency and stability requirements. Consider the thermal environment, as the component supports extended temperature ranges up to 105°C. Evaluate the PCB space constraints against the SM3030-6 package dimensions. Ensure the driving circuit can accommodate the specified load capacitance of 2.5 pF. Verify compatibility with SMD/SMT assembly processes during manufacturing planning.
