Resonators Procurement Notes

Verify the specific load capacitance requirement (27 pF vs 33 pF) against the target circuit design before procurement, as this parameter significantly impacts oscillator stability. Confirm that the SMD package dimensions align with the PCB footprint constraints. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required for moderate precision timing needs. It is suitable for designs where space is limited due to its compact SMD form factor. Consider the ±0.5% frequency tolerance to ensure compatibility with the host controller's clock input requirements. Evaluate the thermal performance to confirm suitability for the intended operating environment.

Resonators Part Context

This part belongs to the CSTLS_G series of CERALOCK ceramic resonators from Murata Electronics. These components are engineered to replace quartz crystals in applications where size, cost, and ease of assembly are prioritized over ultra-high frequency stability. The series offers various frequency options and package types to support diverse embedded system designs.

Resonators Replacement Considerations
