Resonators Procurement Notes

Verify the specific suffix designation against official RFMi documentation to ensure correct frequency tolerance and packaging configuration. Confirm that the required load capacitance matches the circuit design specifications. Ensure compatibility with standard reflow soldering profiles for the specified surface-mount package type.

Resonators Selection Notes

Select this component when a dedicated SAW resonator is required for the 433.92 MHz ISM band. Consider the 32 ppb stability requirement and the physical dimensions of the SM5035-4 package. Evaluate the thermal performance requirements against the -40°C to +85°C operating range before finalizing the design.

Resonators Part Context

This part belongs to the RO series of SAW resonators from RFMi. These components are engineered for high-frequency applications requiring stable oscillation without active tuning elements. The series supports various ISM band frequencies tailored for consumer electronics and industrial telemetry.

Resonators Replacement Considerations

Cross-reference with other RFMi SAW resonators in the same package family. Verify equivalent electrical parameters such as insertion loss and frequency stability before substitution.
