Resonators Procurement Notes

Verify the specific suffix 'R0' against official Murata documentation to confirm packaging configuration. Ensure that the selected variant matches the required frequency tolerance and stability specifications for the target application. Cross-reference the part number with current manufacturer lifecycle status to avoid obsolete components.

Resonators Selection Notes

Select this component when a compact, low-cost clock source is required for microcontrollers or logic ICs. The integrated capacitor eliminates external tuning requirements. Verify that the 20 MHz frequency aligns with system timing needs and that the 80 Ohm impedance is compatible with the driving gate input characteristics.

Resonators Part Context

This part belongs to the CERALOCK CSTCW series, which are small-cap chip type ceramic resonators. These devices leverage piezoelectric properties of polycrystalline ceramic materials to generate precise frequencies. The series is designed for surface-mount assembly, offering a smaller footprint compared to traditional quartz crystals while maintaining adequate stability for general-purpose digital applications.
