Resonators Procurement Notes

Verify that the target application circuit matches the specified 39 pF internal load capacitance to ensure accurate oscillation frequency. Confirm that the required operating environment falls within the -20°C to +80°C thermal limits. Ensure the PCB layout accommodates the specific 4.5 mm x 2 mm SMD footprint dimensions provided in the official datasheet.

Resonators Selection Notes

Select this component when a cost-effective, stable clock source is needed for low-frequency digital systems. It serves as a direct alternative to crystal oscillators where strict phase noise specifications are not critical. Consider the ±0.5% tolerance for precision timing requirements and verify compatibility with the host controller's input impedance characteristics.

Resonators Part Context

This part belongs to the CSTCR_G series of CERALOCK ceramic resonators. These components are engineered to replace traditional quartz crystals in applications requiring moderate frequency accuracy. The series provides a balance between performance and size, utilizing Murata's proprietary ceramic technology for reliable mass production.

Resonators Replacement Considerations

Compatible substitutes include CSTCR4M00G55-R0 (4.0 MHz) and CSTCR4M55G55-R0 (4.55 MHz) from the same family. Cross-model replacement requires verification of the new component's specific load capacitance and frequency tolerance against the original circuit design parameters.
