Crystals Procurement Notes

Verify the specific suffix 'CKR' against the manufacturer's official datasheet to confirm packaging and tape/reel specifications. Ensure the required frequency tolerance of ±10ppm aligns with the target circuit design constraints. Confirm that the 8pF load capacitance matches the oscillator circuit requirements. Check for any updated lifecycle status or obsolescence notices from CTS-Frequency Controls prior to finalizing procurement plans.

Crystals Selection Notes

Select this component when a 20MHz fundamental frequency with ±10ppm stability is required in a compact 2.0x1.6mm footprint. The 100 Ohm ESR and 8pF load capacitance must match the host oscillator circuit parameters. Consider the -20°C to +70°C operating range suitability for the intended application environment. Verify compatibility with surface mount assembly processes.

Crystals Part Context

This part belongs to the 402 Series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequencies in a standardized 4-SMD no-lead package.
