Resonators Procurement Notes

Verify the specific suffix 'B0' against official Murata documentation to confirm package dimensions and termination style. Ensure design compatibility with the 30 Ohm ESR specification for the target oscillator circuit. Check current availability status as distribution channels may vary.

Resonators Selection Notes

Select this component when moderate frequency stability is acceptable and cost reduction is prioritized over high-precision quartz alternatives. Confirm that the 455 kHz frequency aligns with system requirements and that the SIP-2 package fits the PCB layout constraints.

Resonators Part Context

This part belongs to the CSBLA series of ceramic resonators, which are widely used in consumer electronics. It replaces traditional quartz crystals in applications where size, cost, and ease of assembly are critical factors, offering a compact alternative for standard clock frequencies.

Resonators Replacement Considerations

Direct substitution requires verifying oscillator circuit compatibility due to differences in ESR and temperature stability compared to quartz crystals. Consult Murata's official cross-reference guides for validated alternatives if this specific variant is unavailable.
