Crystals Procurement Notes

Verify the specific suffix IKR against official CTS documentation to confirm tape and reel packaging requirements. Ensure design-in compatibility with target load capacitance values. Confirm that the fundamental mode specification aligns with circuit topology. Check for any recent lifecycle status changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with ±20ppm stability. The 8pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR for drive level sensitivity. The 4-SMD footprint requires appropriate PCB land pattern design. Verify thermal performance within the specified -40°C to +85°C range for the intended application environment.
