Resonators Procurement Notes

Verify that the ordering suffix matches the required packaging format, such as cut tape or reel, as specified in the official datasheet. Confirm that the load capacitance value aligns with the target oscillator circuit requirements. Ensure compliance with RoHS directives for the specific production batch. Cross-reference the manufacturer part number against authorized distributor lists to avoid counterfeit components.

Resonators Selection Notes

Select this component when a stable 7 MHz reference is required for embedded systems. The integrated capacitor reduces external component count compared to discrete crystal solutions. Consider the operating temperature range and mechanical dimensions for PCB layout constraints. Evaluate the motional resistance against the oscillator driver strength specifications.

Resonators Part Context

This part belongs to the CSTCR series of ceramic resonators, which are designed as cost-effective alternatives to quartz crystals. The CERALOCK branding indicates Murata's proprietary technology for miniaturized resonators. These components are widely used in applications where moderate frequency accuracy is sufficient.

Resonators Replacement Considerations

Direct substitutes include other Murata ceramic resonators with identical 7 MHz frequency and 39 pF load capacitance, such as the CSTCR7M00G53-R0 if the package height variation is acceptable. Verify pin compatibility and electrical parameters before substitution.
