Resonators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging options such as cut tape or reel. Confirm that the ±0.2% frequency stability meets the target application's timing requirements. Check RoHS compliance status against current regulatory standards for the destination market. Ensure the SMD footprint dimensions align with the PCB layout specifications before finalizing procurement.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is needed for microcontroller clock sources. The built-in capacitor eliminates the need for external load capacitors, reducing board space. Consider the ±0.5% tolerance if higher precision than standard ceramic resonators is required. Verify that the operating temperature range of -20°C to +80°C covers the environmental conditions of the end product.

Resonators Part Context

This part belongs to the CERALOCK CSTCR series of small-cap chip type ceramic resonators. These components are designed specifically for use as time base oscillators in microcomputers and embedded systems. The series provides a balance between performance and size, offering better stability than generic ceramic resonators while maintaining a smaller footprint than traditional quartz crystals.

Resonators Replacement Considerations

Direct substitutes within the same series include parts with identical frequency and package dimensions but different tolerances or temperature ranges. Cross-reference with other manufacturers' 5 MHz ceramic resonators featuring built-in 39 pF capacitors and similar SMD footprints. Ensure electrical parameters such as impedance and stability match the original design requirements.
