Resonators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required frequency tolerances and packaging configurations. Confirm that the selected variant matches the intended load capacitance and thermal requirements for the target application environment before finalizing procurement orders.

Resonators Selection Notes

Select this component when a fixed-frequency SAW resonator is required for 433 MHz ISM band applications. Ensure the circuit design accommodates the specified 2.4 pF load capacitance and verify that the PCB layout supports the SM5035-4 footprint dimensions for proper surface mounting and thermal management.

Resonators Part Context

This part belongs to the RFMi RO series of timing and frequency products, which includes SAW resonators and filters. The series targets emerging wireless applications requiring reliable frequency control. The RO3101A-14 specifically addresses needs for compact, cost-effective solutions in short-range radio frequency transmission systems.

Resonators Replacement Considerations

Consult official substitution lists for compatible SAW resonators with identical 433.92 MHz frequency and SM5035-4 package dimensions. Verify electrical parameters such as load capacitance and stability before replacing to maintain system performance integrity.
