Crystals Procurement Notes

Verify the specific suffix IKR against official CTS documentation to confirm pin configuration and termination style. Ensure the load capacitance requirement matches the target circuit design. Confirm RoHS3 compliance status through current manufacturer declarations before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±20ppm stability is required in a small form factor. The 8pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 100 Ohm ESR limit for drive level sensitivity in the application design.

Crystals Part Context

This part belongs to the CTS 402 series, which provides standard seam-welded SMD crystals. The series offers various frequencies and load capacitances within the same 2x1.6mm footprint, allowing for design flexibility while maintaining consistent mechanical dimensions across different frequency options.

Crystals Replacement Considerations

Direct substitutes include 402F2001XILR and 402F20022ILR from CTS-Frequency Controls. Verify that alternative suffixes match the exact load capacitance and package orientation requirements.
