Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to ensure correct electrical characteristics and package configuration. Confirm RoHS compliance status and lead-free requirements prior to procurement. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Ensure storage and handling procedures align with moisture sensitivity levels specified in the datasheet.

Selection Notes

Select this component when a stable 318 MHz reference is required in space-constrained designs. Consider the 32 ppb stability specification for applications demanding precise frequency control within the -40°C to +85°C range. Evaluate the 2.9 pF load capacitance requirement against circuit design parameters. Compare against alternative SAW resonators if different frequency points or stability metrics are needed.

Part Context

The RO3118A-1 belongs to the RFMi family of SAW resonators, which are engineered for digital and wireless applications. RFMi, now part of Akoustis Technologies, specializes in SAW, crystal, and ceramic components. This series targets markets requiring reliable frequency control in portable and industrial electronics, leveraging advanced acoustic wave propagation for performance.

Replacement Considerations

Consult official substitution guides from Akoustis/RFMi for direct replacements. Verify that any substitute matches the 318 MHz frequency, 2.9 pF load capacitance, and 32 ppb stability specifications. Ensure the replacement maintains the same surface-mount package dimensions and operating temperature range.
