Resonators Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct frequency tolerance and packaging configuration. Confirm that the required load capacitance matches the target circuit design, as this model includes a fixed 5 pF internal capacitor. Check for RoHS and REACH compliance status prior to integration into regulated assemblies.

Resonators Selection Notes

Select this component when a precise 20 MHz reference is required with tight initial tolerance. The integrated 5 pF capacitor eliminates external tuning components, reducing board space. Ensure the application environment stays within the specified -40°C to +125°C range. Consider the 40-ohm impedance for proper oscillator circuit matching.
