Resonators Procurement Notes

Verify the specific suffix GH5L000R0 against the manufacturer's latest datasheet to confirm package dimensions and termination type. Ensure the required frequency tolerance of ±0.07% aligns with system requirements. Check RoHS compliance status via official documentation before integration. Confirm availability through authorized distributors as lead times may vary.

Resonators Selection Notes

Select this component when a precise 4.915 MHz reference is needed with minimal external components. The 39 pF internal capacitance matches common microcontroller input requirements. Consider the -20°C to +85°C range for industrial or consumer electronics. Compare against crystal oscillators if lower phase noise is required, though this resonator offers cost and size advantages.

Resonators Part Context

This part belongs to the CSTNR series of CERALOCK ceramic resonators. These devices are engineered to replace traditional quartz crystals in applications where moderate accuracy suffices. The series emphasizes miniaturization and ease of assembly for mass production environments.

Resonators Replacement Considerations

Direct substitutes include other Murata parts in the CSTNR series with matching 4.915 MHz frequency and 39 pF capacitance. Verify pin compatibility and thermal characteristics when cross-referencing with alternative manufacturers' offerings.
