Crystals Procurement Notes

Verify the specific suffix 'CKR' against official datasheets to confirm tape and reel packaging requirements. Ensure the load capacitance matches the circuit design specifications. Check current availability status as supply conditions may vary. Confirm moisture sensitivity level handling procedures during storage and reflow processes.

Crystals Selection Notes

Select this component when a 27 MHz fundamental crystal is required for space-constrained designs. The 8 pF load capacitance must align with the oscillator circuit's total capacitive load. Consider the ±15 ppm stability for general-purpose timing needs. Verify the 4-SMD package size fits the PCB layout constraints.
