RO3103D

Resonators Overview

The RO3103D is a surface-mount resonator manufactured by RFMi, designed for frequency control in wireless communication systems. It operates at a nominal frequency of 418.075 MHz and utilizes the SM3838-6 package with SMD/SMT termination types. The component provides exceptional frequency stability of 32ppb over an operating temperature range of -40°C to 85°C. This performance supports reliable clocking within RF subsystems, ensuring signal integrity across various digital and wireless applications.

Resonators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required tolerance and temperature specifications. Confirm that the SM3838-6 package dimensions align with the target PCB layout constraints. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market before finalizing procurement orders.

Resonators Selection Notes

Select this resonator when designing systems requiring stable operation within LTE, ISM, GPS, or GNSS bands. The 32ppb stability rating makes it appropriate for applications demanding precise timing accuracy. Ensure the design accommodates the SM3838-6 footprint and accounts for the specified -40°C to 85°C operational range during thermal analysis.

Resonators Part Context

RFMi, now part of Akoustis Technologies, specializes in radio frequency components based on SAW, crystal, and ceramic technologies. The RO3103D belongs to their resonator product line, which serves as critical frequency control elements in transmitters for low-power and wireless communications devices.

Resonators Replacement Considerations

Consult official substitution guides for compatible single-port or dual-port resonators from the same family. Verify equivalent frequency, package size, and stability metrics before considering alternative part numbers.
