Resonators Procurement Notes

Verify the specific suffix 'Z' against official documentation to confirm compliance with regional environmental standards or material composition requirements. Ensure the selected load capacitance matches the target oscillator circuit design specifications to maintain frequency accuracy within the stated tolerance limits.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required for non-critical timing applications. The 5 pF load capacitance requirement necessitates careful PCB layout and external capacitor selection to achieve the specified 20 MHz center frequency without significant deviation.

Resonators Part Context

This part belongs to the CSTLS_X series of Murata ceramic resonators. These components are designed as compact, low-cost replacements for quartz crystals in applications where extreme stability is not mandatory. The series offers various frequencies and package options to suit diverse embedded system designs.

Resonators Replacement Considerations

Direct pin-compatible substitutes include other Murata CSTLS series parts with matching 20 MHz frequency and 5 pF load capacitance. Verify that any replacement maintains the same third-harmonic operation mode and physical dimensions for seamless board integration.
