Resonators Procurement Notes

Verify the specific suffix (e.g., -16) against official RFMi documentation to confirm exact frequency and tolerance specifications. Ensure compatibility with existing PCB footprint and reflow soldering profiles. Cross-reference datasheet parameters for thermal management requirements before finalizing procurement orders.

Resonators Selection Notes

Select this component for applications requiring precise 315 MHz reference frequencies with tight tolerance constraints. Consider the surface-mount package type for automated assembly processes. Evaluate the operating temperature range against the intended deployment environment to ensure long-term reliability and consistent performance under thermal stress.

Resonators Part Context

This part belongs to the RFMi SAW resonator family, which provides passive frequency-selective components for radio frequency circuits. These devices are engineered to replace bulkier crystal or ceramic filters in modern wireless designs, offering superior size reduction while maintaining high Q-factor characteristics essential for signal integrity.

Resonators Replacement Considerations

Direct substitutes include other 315 MHz SAW resonators from manufacturers like Murata or Abracon, provided pinout and electrical parameters match. Verify that alternative parts meet the same 32 ppb tolerance and 4.1 pF load capacitance requirements to maintain circuit performance without redesign.
