Resonators Procurement Notes

Verify the specific suffix R1 against official Murata documentation to confirm tape and reel packaging requirements. Ensure the target application frequency matches the 921 kHz specification precisely. Check RoHS compliance status through current datasheets as product specifications may evolve over time.

Resonators Selection Notes

Select this component when a precise 921 kHz reference is required for microcontroller or logic clock inputs. Consider the 2-SMD gull wing footprint for PCB layout constraints. Evaluate the ±0.3% tolerance against system timing accuracy requirements before finalizing the design.

Resonators Part Context

This part belongs to the Murata CSBFB series of ceramic resonators. These components are engineered to replace discrete crystal oscillator setups by integrating necessary capacitive elements within the package. The series targets cost-sensitive applications requiring reliable frequency stability without complex external tuning networks.

Resonators Replacement Considerations

Direct substitutes include other Murata ceramic resonators with identical 921 kHz frequency and compatible package dimensions. Verify that alternative parts maintain the same ±0.3% tolerance and load capacitance specifications to ensure circuit compatibility.
