Resonators Procurement Notes

Verify that the specific order matches the CM20M00000S022 part number exactly, as TGS produces various ceramic resonators with differing frequencies and capacitance values. Confirm the package type corresponds to the 3731 SMD form factor and ensure the required frequency tolerance of ±0.3% aligns with the application's timing requirements before finalizing procurement.

Resonators Selection Notes

Select this component when a cost-effective timing solution with moderate stability is required for consumer electronics or industrial controls. The built-in capacitor eliminates external load components, reducing board space. Ensure the operating environment stays within the specified -25°C to +85°C range, as wider temperature applications may require higher-stability crystal oscillators.

Resonators Part Context

This device belongs to the CRTV Series of ceramic resonators from TGS Crystals Ltd. Ceramic resonators offer a balance between performance and cost, serving as alternatives to quartz crystals where extreme precision is not critical. The 3731 type indicates a standard small-footprint surface mount package commonly used in compact electronic assemblies.

Resonators Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 22 pF internal capacitance, and 3731 SMD package. Verify ESR compatibility and temperature range limits. Cross-reference with other manufacturers' ceramic resonators using identical electrical parameters and physical dimensions to ensure pin-out and footprint compatibility.
