Crystals Procurement Notes

Verify the specific suffix 'CKR' against official CTS documentation to confirm packaging and material specifications. Ensure the target application circuit matches the 8 pF load capacitance requirement. Confirm that the ±10 ppm stability meets system timing accuracy needs. Check for any end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental mode crystal is required in a small footprint. The 60 Ohm ESR limit suits standard oscillator circuits. Consider the -20°C to +70°C operating range for commercial environments. Compare against higher stability variants if tighter tolerances are necessary for the specific design constraints.
