Crystals Procurement Notes

Verify the specific suffix 'CKR' against the official CTS datasheet to confirm the exact load capacitance and ESR values, as these parameters vary across the 402 series. Ensure the ordering suffix matches the required packaging format, typically tape and reel for this designation. Cross-reference the manufacturer part number directly with the supplier's documentation to avoid discrepancies in electrical specifications or environmental compliance status.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required with ±15 ppm stability. The 8 pF load capacitance must match the oscillator circuit requirements. The 60 Ohm ESR is suitable for standard CMOS oscillator interfaces. Verify that the -20°C to +70°C temperature range meets the application's environmental constraints before finalizing the design.

Crystals Part Context

This part belongs to the CTS 402 series of miniature crystals. The series offers various frequencies and package sizes, all sharing similar surface-mount footprints. The 402F384XXCKR specifically targets applications requiring high-frequency precision in small form factors, distinguishing it from larger through-hole or older SMD variants.

Crystals Replacement Considerations

Direct substitutes within the same series include 402F384XXCKT and 402F384XXCJR. Verify that alternative suffixes maintain the identical 8 pF load capacitance and 60 Ohm ESR. Packaging differences may exist between reel types; ensure mechanical compatibility with existing pick-and-place equipment.
