Resonators Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical parameters and packaging configuration. Ensure the ordering part number matches the required frequency tolerance and load capacitance for your application. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Resonators Selection Notes

Select this component when a precise 7.99 MHz reference is required in space-constrained designs. Compare the 15 pF load capacitance against the microcontroller's internal or external capacitor requirements. Evaluate the thermal performance within the specified -20°C to +80°C range relative to the target environment.

Resonators Part Context

This device belongs to the CERALOCK series of ceramic resonators. It serves as a cost-effective alternative to quartz crystals by integrating the resonant element and capacitors into a single surface-mount package. This integration reduces board space and simplifies assembly compared to discrete crystal solutions.

Resonators Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Ensure any replacement maintains the 7.99 MHz frequency and compatible load capacitance.
