Resonators Procurement Notes

Verify the specific suffix designation against official documentation to confirm exact frequency tolerance and load capacitance requirements. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the delivered components match the specified SM5035-4 package dimensions and RoHS compliance status prior to integration into production lines.

Resonators Selection Notes

Select this component when a precise 315.05 MHz reference is required for ISM band applications. The choice depends on the necessity for a low-profile surface-mount form factor compatible with automated assembly processes. Evaluate the thermal performance requirements against the specified -40°C to +85°C operational range to ensure reliability under expected environmental conditions.

Resonators Part Context

This part belongs to the RO series of SAW resonators from RFMi, an Akoustis brand. The series utilizes surface acoustic wave technology to provide frequency control solutions. These components are designed for digital and wireless communication applications requiring stable oscillation frequencies in compact packages.

Resonators Replacement Considerations

Cross-reference with other RO3073A variants such as RO3073A-16 or RO3073A-10 if different frequency tolerances or package configurations are acceptable. Verify electrical compatibility before substitution.
