Resonators Procurement Notes

Verify the specific suffix against official RFMi 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 before integration into production lines.

Resonators Selection Notes

Select this component when a precise 315.05 MHz reference is required for ISM band applications. The 4.1 pF load capacitance dictates circuit matching network design. Verify thermal stability needs against the -40°C to +85°C range. Consider the small form factor for space-constrained PCB layouts requiring SMD termination.

Resonators Part Context

Part of the RO series SAW resonators from RFMi. Designed for cost-effective frequency control in consumer and industrial electronics. Utilizes standard surface-mount packaging for automated assembly compatibility. Provides a stable reference signal for oscillator circuits without external tuning components.

Resonators Replacement Considerations

Cross-reference with RO3073A-1 or RO3073A-11 for similar 315 MHz variants. Verify frequency accuracy differences between suffixes. Ensure package dimensions and electrical parameters match the original design requirements before substitution.
