Resonators Procurement Notes

Verify the specific suffix 'Z' against the official Murata datasheet to confirm compliance with RoHS and REACH SVHC requirements. Ensure the ordering part number matches the exact frequency and tolerance specifications required for the target application. Cross-reference the package type and reeling format with manufacturing guidelines to prevent handling errors during assembly.

Resonators Selection Notes

Select this component when a precise 4.19 MHz timing source is required with tight initial tolerance. The wide operating temperature range supports deployment in harsh environments. Verify that the system design can accommodate the 15 pF internal load capacitance. Consider the SMD form factor for automated placement processes.

Resonators Part Context

This part belongs to the CSTCR_G series of CERALOCK ceramic resonators. These components utilize piezoelectric ceramic multi-crystals to generate mechanical resonance. They serve as cost-effective alternatives to quartz crystals by eliminating the need for external tuning capacitors and reducing board space requirements.

Resonators Replacement Considerations

CSTCR4M19G55Z-R0: Similar frequency but different load capacitance (39 pF vs 15 pF). CSTCR4M19G53B-R0: Different series variant with distinct load capacitance characteristics.
