Crystals Procurement Notes

Verify the specific suffix 'KR' against the manufacturer's current datasheet to confirm tape and reel packaging specifications and lead frame material. Ensure the selected variant matches the required load capacitance of 8pF for your circuit design. Check for any recent lifecycle status updates or alternative package options from CTS-Frequency Controls before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is needed with tight tolerance requirements. The 60 Ohm ESR value should be compatible with the driving circuit's oscillation conditions. Consider the 8pF load capacitance requirement to ensure accurate frequency calibration without additional external capacitors. Verify thermal performance meets the application's environmental constraints.
