Crystals Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging options such as tape and reel or cut tape. Confirm that the lead time aligns with project schedules, as manufacturing delays may occur due to high demand. Ensure the selected variant matches the exact electrical specifications required by the design.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency is required with moderate stability. The 12 pF load capacitance must match the oscillator circuit design. Consider the 2-SMD package size for board space constraints. Verify ESR limits against the driving circuit capabilities to ensure proper oscillation startup.
