Procurement Notes
Verify the specific manufacturer designation, as documentation references both RFMi and Murata Manufacturing Co., Ltd. Ensure the ordering suffix matches the required frequency tolerance and package variant. Confirm RoHS compliance status through official datasheets prior to procurement to meet regulatory requirements.
Selection Notes
Select this component for applications requiring stable output power across wide temperature ranges from -40°C to 105°C. Consider the 2.5 pF load capacitance requirement when designing matching networks. Verify that the 433.92 MHz center frequency aligns with target band specifications for ISM or LTE implementations.
Part Context
This SAW resonator belongs to a family of components operating within a 30MHz to 3.7GHz frequency range. These devices are engineered for low resistance ratings and are suitable for various wireless communication standards. The RO3101E-20 specifically targets the 433 MHz region, offering a compact solution for signal filtering and frequency control.
Replacement Considerations
Check for variants such as RO3101E-4 or RO3101E-14 if different frequency tolerances or package options are required. Cross-reference with Murata Manufacturing Co., Ltd. documentation to ensure functional equivalence, as some sources list Murata as the manufacturer for similar part numbers.
