Resonators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before ordering. Confirm that the 3-SMD non-standard package dimensions align with the PCB footprint guidelines provided in the official datasheet. Ensure the operating temperature range meets the environmental conditions of the final application. Check for any recent lifecycle status updates or recommended alternate part numbers from Murata to ensure long-term supply availability.

Resonators Selection Notes

Select this component when a cost-effective, stable clock source is needed for digital logic circuits. The 4.5 MHz frequency and ±0.5% tolerance make it suitable for general-purpose timing applications. Consider the 15 pF load capacitance requirement to ensure proper oscillation with the host controller. Evaluate the thermal performance within the specified -20°C to +80°C range to guarantee reliability under operational stress.
